Description
The IBM0436A4CBLBB, IBM0418A4CBLBB,
IBM0418A8CBLBB, and IBM0436A8CBLBB
SRAM
S
are Synchronous Pipeline Mode, high-per-
formance CMOS Static Random Access Memories
that are versatile, have wide I/O, and achieve 3.0ns
cycle times. Differential CK clocks are used to ini-
tiate the read/write operation and all internal opera-
tions are self-timed. At the rising edge of the CK
clock, all Addresses, Controls, and Data Ins are reg-
istered internally. Data Outs are updated from out-
put registers off the next rising and falling edge of
the K clock, hence the Double Data Rate. Internal
Write buffers allow write data to follow one cycle
after addresses and controls. The chip is operated
with a single +2.5V power supply and is compatible
with HSTL I/O interfaces.
