Synchronous DRAM Memory 64Mbit (4Mx16bit)
HY57V641620E(L/S)T(P)-xI Series
DESCRIPTION
The Hynix HY57V641620E(L/S)T(P) series is a 67,108,864bit CMOS Synchronous DRAM, ideally suited for the memory
applications which require wide data I/O and high bandwidth. HY57V641620E(L/S)T(P) is organized as 4banks of
1,048,576x16.
HY57V641620E(L/S)T(P) 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(se-
quential 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 re-
stricted by a '2N' rule)

DESCRIPTION
The system clock input. All other inputs are registered to the
SDRAM on the rising edge of CLK
Controls internal clock signal and when deactivated, the SDRAM will
be one of the states among power down, suspend or self refresh
Enables or disables all inputs except CLK, CKE, UDQM and LDQM
Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
Row Address: RA0 ~ RA11, Column Address: CA0 ~ CA7
Auto-precharge flag: A10
RAS, CAS and WE define the operation
Refer function truth table for details
Controls output buffers in read mode and masks input data in write
mode
