DEVICE OVERVIEW
I
SSI’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.
