DEVICE OVERVIEW

ISSI’s 128-Mbit DDR SDRAM achieves high-speed data

transfer using pipeline architecture and two data word

accesses per clock cycle. The 134,217,728-bit memory

array is internally organized as four banks of 32M-bit to

allow concurrent operations. The pipeline allows Read

and Write burst accesses to be virtually continuous, with

the option to concatenate or truncate the bursts. The

programmable features of burst length, burst sequence

and CAS latency enable further advantages. The device

is available in 16-bit data word size. Input data is regis-

tered on the I/O pins on both edges of Data Strobe

signal(s), while output data is referenced to both edges of

Data Strobe and both edges of CK. Commands are

registered on the positive edges of CK. Auto Refresh,

Active Power Down, and Pre-charge Power Down modes

are enabled by using clock enable (CKE) and other

inputs in an industry-standard sequence. All input and

output voltage levels are compatible with SSTL 2.
