Fujitsu Introduces 128 Megabit NOR-type Flash Memory
Adopts Advanced 0.17 Micron Process with 32-bit Data Transfer
for High-Speed, High-Function Performance
|
Tokyo, November 15, 2001---Fujitsu Limited today unveiled a new,
128-megabit NOR-type(*1) flash memory device, the MBM29PDL1280F.
Manufactured using advanced 0.17 micron process technology and
developed in collaboration with Advanced Micro Devices (AMD) of the
U.S., the new device boasts high-speed 32-bit data transfer and
incorporates page-mode(*2) and dual operation(*3) functionality.
In recent years there have been major advances in the processing
speeds of such appliances as car-navigation systems, printers and
mobile phones, as well as increasing functionality for
communications devices. This has created demand for faster
processors used in such systems, and data transfer speeds are
moving from the 8-bit/16-bit to 16-bit/32-bit and even 64-bit.
Likewise, for flash memory, there has been a corresponding demand
for wider data bus to support higher speed and larger data volumes.
Fujitsu's new device is designed for faster read speed, achieving
25 nanoseconds (in page-mode), the fastest of any 128-Mbit device.
In addition, by expanding the data bus from 8-bit/16-bit to
16-bit/32-bit, larger blocks of data can be processed at one time,
thereby improving ease of integration with microprocessors used in
electronic products. Furthermore, the adoption of the dual
operation function enables the device to simultaneously perform
read/write/erase operations, and the inclusion of the
acceleration(*4) feature allows faster writing of large data
volumes on to flash memory prior to mounting on the printed circuit
board.
Fujitsu has also included a number of security functions, including
Hi-ROM(*5), which prevents illegal copying of large files,
write-protect(*6) hardware-based protection of the boot-block
sectors (where system software is located), and new sector
protection(*7).
The new product will be manufactured at the JV3 facility at
Fujitsu-AMD Semiconductor Ltd., a joint venture between Fujitsu and
AMD, located in Aizu-Wakamatsu, Japan. This facility began
producing 64-Mbit dual operation flash earlier this month.

[Glossary]
- *1
- NOR-type flash memory: the most common type of flash memory.
Supports high-speed random access reads with the parallel NOR
memory cell architecture.
- *2
- Page-mode: enables fast reads based on a partial address.
- *3
- Dual operation: permits simultaneous read/write/erase
operations.
- *4
- Acceleration: shortens data-write time when applying high
voltage, for faster write operations than usual.
- *5
- Hi-ROM (Hidden Read-Only Memory): a region of memory used for
security codes and fixed data.
- *6
- Write protection: provides hardware-level protection to the
sectors above and below a given address from inadvertent rewrites.
- *7
- New sector protection: In addition to the existing
sector-protection technique based on applied high voltage, this new
type of sector protection makes it possible to protect all sectors
and preserve the data already written to them by simply entering a
set command.
- *8
- SSOP (Shrink Small-Outline Package): A type of surface mount
type package.
- *9
- FBGA (Fine-Pitch Ball Grid Array): a type of surface mount type
package that uses ball-shaped terminals with spacing of less than
0.8 mm.
