Features

Description

The V58C2512(804/404/164)SD is a four bank DDR

DRAM organized as 4 banks x 16Mbit x 8 (804), 4 banks x

32Mbit x 4 (404), 4 banks x 8Mbit x 16 (164). The

V58C2512(804/404/164)SD achieves high speed data

transfer rates by employing a chip architecture that

prefetches multiple bits and then synchronizes the output

data to a system clock.

All of the control, address, circuits are synchronized

with the positive edge of an externally supplied clock. I/O

transactions are occurring on both edges of DQS.

Operating the four memory banks in an interleaved

fashion allows random access operation to occur at a

higher rate than is possible with standard DRAMs. A se-

quential and gapless data rate is possible depending on

burst length, CAS latency and speed grade of the device.

High speed data transfer rates with system frequency

up to 250MHz
