Description
The 4Mb and 8Mb SRAMs—IBM0436A41BLAB,
IBM0418A41BLAB, IBM0418A81BLAB, and
IBM0436A81BLAB—are Synchronous Pipeline
Mode, high-performance CMOS Static Random
Access Memories that are versatile, wide I/O, and
can achieve 3ns 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 device is operated with a single
+2.5V power supply and is compatible with HSTL
I/O interfaces.
