NEW SYNCHRONOUS DRAMS TARGETED FOR PC MAIN MEMORY APPLICATIONS

Monolithic and Module Versions To Be Offered At Lower Cost

Tokyo, Japan and Mountain View, CA (July 26, 1995)

NEC Electronics Inc. and NEC Corporation today announced the intent to
produce 16 Megabit Synchronous DRAMs designed specifically for use in
personal computer main memory applications. The high performance parts
will be offered in both monolithic and 168-pin Dual In-Line Memory Module
(DIMM) versions and are expected to be offered for up to ten percent less
than today's standard synchronous DRAMs, making them ideally suited for
the high volume main memory market.

"Today, fast-page and hyper-page (also known as EDO) DRAMs are the most
commonly used devices for PC main memory," said Cecil Conkle, NEC
Electronics Inc. senior product marketing manager for memory. "However, in
order to support the new higher-speed processors, DRAMs need to be even
faster, without substantially increasing system costs -- the solution is
new generation, or synchronous, DRAMs. NEC is progressing toward our
customers' goal of only a five percent price premium for these new SDRAMs,
compared to fast-page DRAMs.

"NEC is a leader in providing synchronous DRAMs to the high-end workstation
market; and we are now taking the next step, driving this technology into
the personal computer arena with these new devices."

Product Features

The new Synchronous DRAMs (SDRAMs) will offer the minimum functions
necessary for main memory applications, which will shorten the testing
cycle, thus reducing overall cost. All of the devices include an LVTTL
interface, operating at 3.3 volts. Operating temperature ranges from 0
degrees Celsius (C) to 70 degrees C.

The SDRAM devices will be provided in the following configurations:

Part #      Organization        Speeds               Package Type
uPD4516421    4M x 4       50, 60, 67, 75 MHz   44-pin TSOP (400 mil)
uPD4516821    2M x 8       50, 60, 67, 75 MHz   44-pin TSOP (400 mil)
uPD4516161    1M x 16      50, 60, 67, 75 MHz   50-pin TSOP (400 mil)

The SDRAM DIMM family will include the following versions:

Organization                   Speeds                   Package Type
1M x 64                  50, 60, 67, 75 MHz             168-pin DIMM
2M x 64                  50, 60, 67, 75 MHz             168-pin DIMM
4M x 64                  50, 60, 67, 75 MHz             168-pin DIMM
2M x 72 (ECC)            50, 60, 67, 75 MHz             168-pin DIMM
4M x 72 (ECC)            50, 60, 67, 75 MHz             168-pin DIMM

Standard features for the new DIMMs include the option of buffered and
unbuffered types, and gold plated contacts.

For comparison, the new devices will offer a CAS latency of 3 versus
latencies of 1, 2 and 3 for today's standard SDRAMs.  Additionally, the
new devices will feature data burst lengths of one and four.

Pricing and Availability

The new SDRAMs and SDRAM DIMMs are expected to be available in sample
quantities September 1995.  Sample pricing will vary depending on
configuration and speed, and will range from $79.55 to $113.65 for the
SDRAMs, and $568.20 to $2272.75 for the SDRAM DIMMs.  Mass production is
expected in the fourth quarter of 1995.
