NEC Develops 64Mb Dual-Operation Flash Memory for Ultra-Low-Power Mobile Applications
-Achieving Top Class Ultra-Low-Power Operation Voltage-
TOKYO September 3rd, 2001 - NEC Corporation
(NEC) (NASDAQ: NIPNY) (FTSE: 6701q.l) (TSE: 6701) announces development of dual-operation
flash memory with page-read function optimized for ultra-low-power mobile applications
such as cellular phones, PDAs (personal digital assistants) and other portable
terminals. NEC's two new 64-megabit (Mb) devices (product name: uPD29F064115 and
uPD29F064215) run on a minimum power supply of 1.65V (1.8V+/-0.15V) - one of the
lowest operation voltages available for flash memory.
Sample shipments are scheduled to begin in October, with a shift to volume
production from January 2002 at a total production amount of one million units
per month. The planned sample price is $50 (USD).
Main features of the new products:
One of the Industry's lowest operation voltages of Vcc=1.65V minimum (1.8V +/-
0.15V) has been achieved. This voltage is one of the lowest voltages for flash
memory products making it ideal for low- power mobile applications.
Page-read function with a high-speed page access time of 30ns (nano-seconds).
The page-read function supports two page modes (4-word random mode and 8-word
sequential access mode) allowing a large improvement on system performance.
Dual operation with 4-bank architecture is employed in order to enhance flexibility.
8Mb + 24Mb + 24Mb + 8Mb bank architecture enables efficient simultaneous read/write
operations, taking into account that the ratio of code and data storage may vary
form application to application. In addition, while program or erase operation
is carried out in one of the four storage banks, read operation from any of the
other three storage banks is possible. Two 8Mb-storage banks contain 4K-word x
8 boot sectors, covering conventional top-boot and bottom-boot architecture in
The uPD29F064115 has a separate 1.8V I/O power supply pin (Vccq) and 3V power
supply pin (Vcc), for systems with 3-volt data bus. The uPD29F064215 operates
at single 1.8V power supply.
The evolution of the internet and wireless mobile systems has introduced new
mobile applications such as next-generation mobile phones and PDAs with wireless
communication function, which requires high performance flash memory with large
density to store code and data and improve speed. To enable the increased functionality
without shortening the operation time the need for low-power consumption, large
density and high-speed flash memory is clear. To meet these calls from the market,
NEC has developed the new 64Mb flash memory with an ultra-low operation at 1.65V,
a page-read mode and dual-operation function ideal for the new wave of mobile
The new devices will be offered as TSOP and FBGA packages, and as stacked multi-chip
packages (S-MCP's), which combine flash memory with mobile specified RAM or SRAM.
