Overview

HY57V28420B(L)T 4Banks x 8M x 4bits Synchronous DRAM DESCRIPTION Preliminary The Hynix HY57V28420B(L)T is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the main memory applications which require large memory density and high bandwidth.
HY57V28420B(L)T is organized as 4banks of 8,388,608x4.
HY57V28420B(L)T 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.
