(9273) in plastic surface mount packages on an epoxy lami-
nate board with pins. The modules are designed to be incor-
porated into large memory arrays.
The modules are configured as single banks or multiple banks
depending on the SRAM used to make the module. Separate
clock are provided for each of the banks. Separate clocks are
provided for each of the SRAMs.
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.

Functional Description
The CYM9270, CYM9271B, CYM9272A, and the CYM9273
are high-performance synchronous memory modules orga-
nized as 64K(9270), 128K(9271B), 256K(9272A), 512K(9273)
by 36 bits. These modules are constructed using either 128K
x 18 SRAMs (9270, 9271B, 9272A) or 256K x 18 SRAMs
