HY57V161610D
2 Banks x 512K x 16 Bit Synchronous DRAM
D E S C R IP T IO N
THE Hyundai HY57V161610D is a 16,777,216-bits CMOS Synchronous DRAM, ideally suited for the main memory
and graphic applications which require large memory density and high bandwidth. HY57V161610D is organized as
2banks of 524,288x16.
HY57V161610D is offering fully synchronous operation referenced to a positive edge 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 band-
width. All input and output voltage levels are compatible with LVTTL.
Programmable options include the length of pipeline (Read latency of 1,2 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 pipeline
design is not restricted by a `2N` rule.)
