The SK Hynix HY57V281620HC(L/S)T is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the main memory applicationswhich require large memory density and high bandwidth. HY57V281620HC(L/S)T is organized as 4banks of 2,097,152x16.

HY57V281620HC(L/S)T is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs aresynchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high bandwidth. All inputand 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 initiatedby a single control command (Burst length of 1,2,4,8, or full page), and the burst count sequence(sequential or interleave). A burst ofread or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burstread or write command on any cycle. (This pipelined design is not restricted by a `2N` rule.)
