CY7C135  
CY7C1342  
4K x 8 Dual-Port Static RAM and 4K x 8  
Dual-Port SRAM with Semaphores  
Functional Description  
Features  
• True Dual-Ported memory cells which allow simulta-  
neous reads of the same memory location  
The CY7C135 and CY7C1342 are high-speed CMOS 4K x 8  
dual-port static RAMs. The CY7C1342 includes semaphores  
that provide a means to allocate portions of the dual-port RAM  
or any shared resource. Two ports are provided permitting  
independent, asynchronous access for reads and writes to  
any location in memory. Application areas include interpro-  
cessor/multiprocessor designs, communications status  
buffering, and dual-port video/graphics memory.  
• 4K x 8 organization  
• 0.65-micron CMOS for optimum speed/power  
• High-speed access: 15 ns  
• Low operating power: ICC = 160 mA (max.)  
• Fully asynchronous operation  
• Automatic power-down  
Each port has independent control pins: chip enable (CE),  
read or write enable (R/W), and output enable (OE). The  
CY7C135 is suited for those systems that do not require  
on-chip arbitration or are intolerant of wait states. Therefore,  
the user must be aware that simultaneous access to a location  
is possible. Semaphores are offered on the CY7C1342 to  
assist in arbitrating between ports. The semaphore logic is  
comprised of eight shared latches. Only one side can control  
the latch (semaphore) at any time. Control of a semaphore  
indicates that a shared resource is in use. An automatic  
power-down feature is controlled independently on each port  
by a chip enable (CE) pin or SEM pin (CY7C1342 only).  
• Semaphoresincludedonthe7C1342topermitsoftware  
handshaking between ports  
• Available in 52-pin PLCC  
• Pb-Free packages available  
The CY7C135 and CY7C1342 are available in 52-pin PLCC.
