Features
Functional Description
The CYM9260, CYM9261, CYM9262, and the CYM9263 are
high-performance synchronous memory modules organized
as 64K(9260), 128K(9261), 256K(9262), or 512K(9263) by 72
bits. These modules are constructed from either 128K x
18(9260,9261B,9262A) or 256K x 18 (9263) SRAMs in plastic

surface mount packages on an epoxy laminate board with
pins. The modules are designed to be incorporated into large
memory arrays.
The module is configured as either one or two banks, where
each bank has separate chip select and output enable con-
trols. Separate clocks are provided for every pair of SRAMs’s.
Multiple ground pins and on-board decoupling capacitors en-
sure high performance with maximum noise immunity.
All components on the cache modules are surface mounted on
a multi-layer epoxy laminate (FR-4) substrate. The contact
pins are plated with 150 micro-inches of nickel covered by 30
micro-inches of gold flash.
