Hitachi's x16/Bit Configuration High-Speed
16M/Bit Synchronous DRAMand 64/Bit Bus
Compatible168/Pin SDRAM Modules

-High-speed bandwidths up to 200 Mbyte/second
for MPEG2 and high-speed image processing-

Hitachi, Ltd. has developed and will release the HM5216165 x16-bit configuration 16M-bit synchronous DRAM, delivering 100 MHz high- speed operation and bandwidths(*1) up to 200-Mbyte/second, for high- speed image processing such as MPEG2(*2) and for use as main memory in workstations and personal computers (PCs). Two 168-pin synchronous DRAM modules-the HB526A164EN (8 Mbytes) and the HB526A 264EN (16 Mbytes)-have also been developed for use as PC main memory, incorporation 16-Mbit synchronous DRAMs and offering 64-bit bus support.

Sample shipments of the HM5216165 chip and the two modules will begin in April 1996 in Japan.

Notes:

1. Bandwidths: Speed at which data is transferred.
2. MPEG2 (Moving Picture Experts Group 2): International standard for moving picture compression and expansion technology. Used in cable TV and digital satellite broadcast set-top boxes, and in DVD players, etc.

Features

1. x16-bit configuration (HM5216165)

The multibit configuration provides a fast maximum bandwidths of 200 Mbyte/second, suitable for MPEG2 and image processing.

2. High-speed reading/writing

With 100 MHz high-speed operation synchronized with the system clock, plus a two bank configuration, the overall operating speed is six to seven times that of a conventional general-purpose RAM product with fast paging, and approximately four times that of an EDO product.
