The SK Hynix HY57V281620E(L/S)T(P) series is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the memoryapplications which require wide data I/O and high bandwidth. HY57V281620E(L/S)T(P) series is organized as 4banks of2,097,152 x 16.

HY57V281620E(L/S)T(P) is offering fully synchronous operation referenced to a positive edge of the clock. All inputs andoutputs are synchronized with the rising edge of the clock input.
The data paths are internally pipelined to achievevery 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 writecycles 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 orcan be interrupted and replaced by a new burst read or write command on any cycle. (This pipelined design is not re-stricted by a '2N' rule)
