Description
The IBM043611QLA and IBM041811QLA 1Mb
SRAMS are Synchronous Pipeline Mode, high performance CMOS Static Random Access Memories
that are versatile, wide I/O, and achieves 5 nsec
cycle times. Differential K clocks are used to initiate
the read/write operation and all internal operations
are self-timed. At the rising edge of the K Clock, all
Addresses, Write-Enables, Sync Select and Data
Ins are registered internally. Data Outs are updated
from output registers off the next rising edge of the K
clock. An internal Write buffer allows write data to
follow one cycle after addresses and controls. The
chip is operated with a single +3.3V power supply
and is compatible with GTL/HSTL I/O interfaces.
