CYM9265/CYM9266  
CYM9267/CYM9268  
PRELIMINARY  
64K/128K/256K/512K x 72 SRAM Modules  
face mount packages on an epoxy laminate board with pins.  
The modules are designed to be incorporated into large mem-  
ory arrays.  
Features  
• Operates at 133 MHz  
• Uses 128K x 18, or 256K x 18 high performance syn-  
chronous SRAMs  
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.  
• 168-position Angled DIMM from Amp p/n 179508-2  
• 3.3V inputs/data outputs  
Multiple ground pins and on-board decoupling capacitors en-  
sure high performance with maximum noise immunity.  
Functional Description  
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.  
The CYM9265, CYM9266, CYM9267, and the CYM9268 are  
high-performance synchronous memory modules organized  
as 64K(9265), 128K(9266), 256K(9267), or 512K(9268) by 72  
bits. These modules are constructed from either 128K x  
18(9265,9266,9267) or 256K x 18(9268) SRAMs in plastic sur-

2. Resistor values for VCCQ=3.3V are R1 = 317Ω and R2 = 351 Ω.  
3. Unless otherwise noted, test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output  
loading of the specified IOL/IOH and load capacitance. Shown in (a) and (b) of AC Test Loads. All measurements are made at room temperature.  
4. tEOZ is specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 500 mV from steady-state voltage.
