HY57V654020B

4 Banks x 4M x 4Bit Synchronous DRAM

DESCRIPTION

The Hynix HY57V654020B is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the main memory applications which

require large memory density and high bandwidth. HY57V654020B is organized as 4banks of 4,194,304x4.

HY57V654020B is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are synchro-

nized 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.)
