2005–2009: 45%-55% annual cost reductions;

SLC MLC (~90% of bits)

200mm 300mm, mega-fabs, automation, immersion lithography

Unprecedented productivity thru rapid technology transitions

2010–2013: 25%-35% annual cost reductions;

MLCX3 (~50% of bits)

NAND technology more challenging at 1x nm, 1y nm

EUV lithography will likely be required below 1x nm

3D R/W (READ/WRITE) MEMORY—SCALABLE CROSS-POINT DIODE ARRAY

Joint development with Toshiba, now proceeding at Yokkaichi

Making good progress with R/W layer, but not yet ready for production

At x8 equivalent, and given our knowhow in 3D diode arrays, we believe 3D R/W is the most likely successor for NAND in the coming decade: could usher second SSD wave

Page 19 Investor Day | February 26, 2010

NAND AND POST-NAND FABS IN COMING DECADE

Existing NAND mega-fabs at 1xnm will be highly depreciated, generating attractive margins and throwing off long tail of cash

New NAND mega-fabs will be pricey (~$8 billion for 200,000 wafers/month), will need to support EUV, will need to adapt to post-NAND technologies production

Industry NAND transition SLCMLC took 3 years (20022005)

Industry transition to post-NAND will be more complex, expect extended period of overlapping NAND and post-NAND designs in production

Page 20 Investor Day | February 26, 2010

HOW WE STACK UP AGAINST NAND COMPETITION

• SanDisk Flash Technology/Intellectual Property: – 32nm: leader in X3, industry‘s most cost effective, 2010 work-horse – 24nm: expect to lead with X3: production work-horse in 2011 – X4: shipping products, but limited applications – Systems, Advanced controllers, AFM (Adaptive Flash Management):

uniquely advantaged relative to competition– Security, Content: leadership position– Die stacking: leading 8 die stacking in high volume (microSD™, iNAND™)

• Scale: Great partnership with Toshiba: – Our Fab 3 + Fab 4 deliver ~ 35% of world‘s NAND output

• Flash Storage is really tough to do well. Leadership requires:– Most advanced semi production technology applied on massive scale– Rapid product innovations and strong IP.

• SanDisk: We do Flash right !

Page 21 Investor Day | February 26, 2010

INTELLECTUAL PROPERTY: STATUSSAMSUNG CROSS-LICENSE: Seven-year patent cross license renewal with estimated effective

rate of the fixed payments and royalties at approximately 50% of recent effective royalty rate

FLASH MEMORY PORTFOLIO: Wall Street Journal‘s Patent Board Scorecard ranked SanDisk # 2

in 2009 among the semiconductor companies it tracks, up from # 4 in 2008 Licensed to ~85% of NAND industry output

CARDS: SD, microSD now account for~85% (and growing) of all cards

sold—royalties shared with SD 3C (Toshiba, Panasonic, SanDisk)

AS YET UNTAPPED LICENSING POTENTIAL: Extensive Systems/controllers, SSD, Mobile Security (content) Fundamental patents in 3D diode arrays (apply to most 3D

approaches)

Page 22 Investor Day | February 26, 2010

OUR FLASH CAPACITY PLANS

• We believe that growing demand should drive a healthy industry-wide supply/demand balance in 2010, likely to continue into 2011

• We are focused on technology upgrades and X3 in Fab 3 and Fab 4

• In 2010/2011 we are planning to acquire our 50% of remaining unused capacity in Fab 4, bringing our captive output to ~2 million 300mm wafers/year. – We will leverage non captive sources when demand exceeds this captive

supply

• We project demand for NAND and 3D R/W to outstrip our captive and non-captive supply sometime in the next few years

• Investment in new captive fab believed premature, will require healthy demand/supply balance and ROIC:– We will evaluate continuously and proceed with caution

FLASH SSD: MASSIVE MARKET IN COMING DECADE

• SSD adoption still in early stages: expect market acceleration in 2011 with 2x nm NAND, tipping point reached with1x nm NAND

• SSD will come in all kinds of form-factors (e.g. thin), optimized for specific usage models, fostering new architectures/innovation

• SSD price elasticity will serve to correct industry excess supply

• We see SSD as playing to our strengths in Systems, IP and captive supply, and expect to be a long term SSD participant

PARTNERING WITH MOBILE NETWORK OPERATORS: SERVICE DISCOVERY CARDS

Historically, carriers have viewed the microSD™ cards as an extension of the phone—like a Bluetooth earpiece.

The Mobile Internet explosion is forcing carriers to find economical solutions to grow their service offerings

SanDisk’s Service Discovery Cards (SDC) leverage unique capabilities (streaming, caching, encrypting) enabled by our system, to act as anextension of the network.

DEFINING SANDISK‘S LONG-TERM TARGET FINANCIAL MODEL (LTFM)

The LTFM is the P&L model we believe best balances:

– Growth, profitability & cash flow

The LTFM is the P&L model we aim to achieve

We will not be in the LTFM every year

– Industry & SanDisk subject to cyclicality

– In some years we will be below the LTFM, and in some years we will exceed the LTFM

Page 212 Investor Day | February 26, 2010

KEY VARIABLES IMPACTING OUR BUSINESS MODEL

• Variability in Pricing–Industry supply/demand environment a key factor

• Timing of Technology Transitions and Mix of X2/X3–Strong track record of execution–Leader in X3

• Mix of Product Revenue and L&R Revenue–Product revenue currently growing faster than L&R revenue

• Mix of Captive/Non-Captive Memory –Higher non-captive mix results in:•Lower gross margins•Less capital investment required to meet demand

• Investment in Post-NAND technology–Requires parallel R&D spending

APPENDICES

• Basis of Presentation for Non-GAAP to GAAP Reconciliations

• Non-GAAP to GAAP Reconciliations for Historical Results

• Non-GAAP to GAAP Reconciliations for Forecasts

Page 224 Investor Day | February 26, 2010

To supplement our condensed consolidated financial statements presented in accordance with generally accepted

accounting principles (GAAP), we use non-GAAP measures of operating results, net income (loss) and net income

(loss) per share, which are adjusted from results based on GAAP to exclude certain expenses, gains and losses.

These non-GAAP financial measures are provided to enhance the user's overall understanding of our current

financial performance and our prospects for the future. Specifically, we believe the non-GAAP results provide useful

information to both management and investors as these non-GAAP results exclude certain expenses, gains and

losses that we believe are not indicative of our core operating results and because it is consistent with the financial

models and estimates published by many analysts who follow the Company. For example, because the non-GAAP

results exclude the expenses we recorded for share-based compensation, the amortization of acquisition-related

intangible assets related to acquisitions of Matrix Semiconductor, Inc. in January 2006, msystems Ltd. in November

2006 and MusicGremlin, Inc. in June 2008, the impairment of goodwill and acquisition-related intangible assets, and

non-cash economic interest expense associated with our cash-settled convertible debt, we believe the inclusion of

non-GAAP financial measures provide consistency in our financial reporting. These non-GAAP results are some of

the primary indicators management uses for assessing our performance, allocating resources and planning and

forecasting future periods. Further, management uses non-GAAP information that excludes certain non-cash

charges, such as impairment of goodwill and acquisition-related intangible assets, amortization of purchased

intangible assets, share-based compensation and non-cash economic interest expense associated with our cash-

settled convertible debt, as these non-GAAP charges do not reflect the cash operating results of the business or the

ongoing results. These measures should be considered in addition to results prepared in accordance with GAAP,

but should not be considered a substitute for, or superior to, GAAP results. These non-GAAP measures may be

different than the non-GAAP measures used by other companies.

Explanation of Difference Between Non-GAAP and GAAP:(3)

(4)

(5)

(6)

Non-GAAP excludes incremental interest expense relating to the non-cash economic interest expense associated with

the Company's cash-settled convertible debt.

Non-GAAP total cost of product revenues excludes estimated share-based compensation expenses and amortization

of acquisition-related intangible assets.

Product gross margin reflects product revenues less total cost of product revenues.

Due to a partial valuation allowance on net deferred tax assets, no estimate of GAAP tax provision rate is possible at

this time.
