HY57V56420B(L)T

4 Banks x 16M x 4Bit Synchronous DRAM

DESCRIPTION

The HY57V56420B is a 268,435,456bit CMOS Synchronous DRAM, ideally suited for the main memory applications which require large

memory density and high bandwidth. HY57V56420B is organized as 4banks of 16,777,216x4.

HY57V56420B is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are synchronized

with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All input and output voltage

levels are compatible with LVTTL.

Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write cycles initiated by

a single control command (Burst length of 1,2,4,8 or full page), and the burst count sequence(sequential or interleave). A burst of read or

write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst read or

write command on any cycle. (This pipelined design is not restricted by a `2N` rule.)
