                    MARVELL(R) TECHNOLOGY GROUP LTD. REPORTS
                    RECORD FOURTH QUARTER FISCAL 2004 RESULTS

                 MARVELL'S BOARD APPROVES A 2 FOR 1 STOCK SPLIT

Sunnyvale, CA. (February 26, 2004) - Marvell(R) Technology Group Ltd. (NASDAQ:
MRVL), the technology leader in the development of extreme broadband
communications and storage solutions, today reported financial results for its
fourth fiscal quarter and year ended January 31, 2004.

Net revenue for the fourth quarter of fiscal 2004 was a record $243.3 million,
an increase of 61% over net revenue of $150.8 million for the fourth quarter of
fiscal 2003 and a 13% sequential increase from net revenue of $215.3 million for
the third quarter of fiscal 2004. Net income under generally accepted accounting
principles (GAAP) was $19.8 million, or $0.14 per share (diluted), for the
fourth quarter of fiscal 2004, compared with a net loss under GAAP of $24.2
million, or $0.20 per share (diluted), for the fourth quarter of fiscal 2003.

Net revenue for the year ended January 31, 2004 was $819.8 million, an increase
of 62% over net revenue of $505.3 million for the year ended February 1, 2003.
Net income under GAAP was $45.5 million, or $0.33 per share (diluted), for the
year ended January 31, 2004, compared with a net loss under GAAP of $72.2
million, or $0.61 per share (diluted), for the year ended February 1, 2003.

Marvell reports net income (loss) and basic and diluted net income (loss) per
share in accordance with GAAP and additionally on a non-GAAP basis, referred to
as pro forma. Pro forma net income, where applicable, excludes the effect of
acquisition-related expenses, amortization of stock-based compensation and
charges related to facilities consolidation. Pro forma net income was $41.3
million, or $0.29 per share (diluted), for the fourth quarter of fiscal 2004,
compared with pro forma net income of $20.3 million, or $0.16 per share
(diluted), for the fourth quarter of fiscal 2003. Shares used in computing pro
forma net income per share for the fourth quarter of fiscal 2004 increased to
144.2 million, compared with 129.3 million for the fourth quarter of fiscal
2003.

Pro forma net income was $130.8 million, or $0.95 per share (diluted), for the
year ended January 31, 2004, compared with pro forma net income of $62.5
million, or $0.48 per share (diluted), for the year ended February 1, 2003.
Shares used in computing pro forma net income per share for the year ended
January 31, 2004 were 138.2 million, compared to 129.8 million for the year
ended February 1, 2003. These non-GAAP measures should be considered in addition
to, and not as a substitute for, the results prepared in accordance with GAAP. A
reconciliation of GAAP net income (loss) to pro forma net income is included in
the financial statements portion of this release as well as on our website in
the Investors section at www.marvell.com.

Marvell's management believes the non-GAAP information is useful because it can
enhance the understanding of the Company's ongoing economic performance and
Marvell therefore uses pro forma reporting internally to evaluate and manage the
Company's operations. Marvell has chosen to provide this information to
investors to enable them to perform comparisons of operating results in a manner
similar to how the Company analyzes its operating results.

"We are pleased to announce the results of another outstanding year and fourth
quarter for Marvell," stated Dr. Sehat Sutardja, Marvell's President and CEO.
"We finished the year with strong momentum and solid positioning in our markets.
Our strong revenue growth in Q4 was largely fueled by the continued adoption of
our Gigabit, Wireless and Storage products. Fiscal 2005 promises to be an
exciting year as our products and new technologies are expected to reach many
new large volume markets and applications such as consumer electronics and power
management."

Revenue for the fourth quarter was a record for Marvell and represented our 25th
consecutive quarter of sequential revenue growth. Also, the 13% sequential
increase in Marvell's fourth quarter revenue was Marvell's 9th consecutive
quarter where sequential revenue growth was greater than 10%. The following is a
review of some of the highlights that occurred during the fourth quarter:

     o    In January, Marvell announced its entrance into the power management
          market with revolutionary Digital Signal Processing (DSP) based
          mixed-signal solutions. Marvell developed a breakthrough in power
          management technology using an innovative DSP based solution that
          allows for the use of extremely small passive components. The
          introduction of this innovative technology comes at a time when
          conventional solutions are struggling to handle the critical issues
          arising in wide range of electronic devices including PCs, Consumer
          and Portable products.

     o    Marvell is driving widespread adoption of WLAN into consumer
          electronic devices by offering the highest performance, lowest power
          and smallest form factor products allowing for the most cost effective
          designs. Marvell is winning numerous designs with large consumer
          electronics OEMs for such applications as cellular handsets, gaming
          devices, PDA's, and emerging home entertainment multimedia client
          devices.

     o    Marvell continues to ramp its Gigabit Ethernet networking
          infrastructure revenues with the continued strong adoption of its
          technology proven Prestera(TM) product family. The Prestera Switch
          family is now in volume production across all market segments of
          Gigabit Ethernet infrastructure switching. Marvell's Prestera can now
          be found in products ranging from high-end chassis metro systems, to
          enterprise class fully managed layer 3 switches, and all the way to
          high-volume unmanaged layer 2 Gigabit desktop switches.

     o    During the fourth quarter, Marvell commenced shipment of Yukon(TM)-EC
          Gigabit Ethernet controllers for use in PCI Express platforms. The
          Yukon-EC is the world's smallest Gigabit Ethernet controller available
          today for desktops, notebooks and servers. Marvell also announced that
          leading motherboard companies Asustek, ECS, Gigabyte and Micro Star
          International all have selected Yukon-EC for their PCI-Express
          motherboards.

     o    Marvell is proud to have been added to the NASDAQ-100 during the
          quarter. The NASDAQ-100 Index is comprised of the 100 largest
          non-financial stocks listed on the NASDAQ Stock Market based on market
          capitalization.


MARVELL'S BOARD APPROVES A 2 FOR 1 STOCK SPLIT

Additionally, Marvell's Board of Directors has approved a 2 for 1 stock split of
the Company's common stock, to be effected pursuant to the issuance of
additional shares. The stock split is subject to shareholder approval of an
increase in the Company's authorized share capital at the Company's 2004 Annual

Marvell's shareholders, Marvell expects the declaration and payment of the
