HY57V161610C
2 Banks x 512K x 16 Bit Synchronous DRAM
DESCRIPTION
THE Hyundai HY57V161610C 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. HY57V161610C is organized as
2banks of 524,288x16.
HY57V161610C 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.)

DESCRIPTION
The system clock input. All other inputs are referenced 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.
Command input enable or mask except CLK, CKE and DQM
Select either one of banks during both RAS and CAS activity.
Row Address : RA0 ~ RA10, Column Address : CA0 ~ CA7
Auto-precharge flag : A10
RAS, CAS and WE define the operation.
