Synchronous DRAM Memory 128Mbit (4Mx16bit *2stack)
HY5V22E(L)M(P) Series
DESCRIPTION
The Hynix HY5V22E(L)M(P) series is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the memory appli-
cations which require wide data I/O and high bandwidth. HY5V22E(L)M(P) is organized as 4banks of 1,048,576 x
32(organized 128M bit SDRAM into two 64M bit SDRAM).
HY5V22E(L)M(P) is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and out-
puts 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(se-
quential or interleave). A burst of r ead 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 re-
stricted by a '2N' rule)
