CY7C024/0241  
CY7C025/0251  
4K x 16/18 and 8K x 16/18 Dual-Port  
Static RAM with SEM, INT, BUSY  
Functional Description  
Features  
• True Dual-Ported memory cells which allow simulta-  
The CY7C024/0241 and CY7C025/0251 are low-power  
CMOS 4K x 16/18 and 8K x 16/18 dual-port static RAMs.  
Various arbitration schemes are included on the CY7C024/  
0241 and CY7C025/0251 to handle situations when multiple  
processors access the same piece of data. Two ports are  
provided, permitting independent, asynchronous access for  
reads and writes to any location in memory. The CY7C024/  
0241 and CY7C025/0251 can be utilized as standalone  
16-/18-bit dual-port static RAMs or multiple devices can be  
combined in order to function as a 32-/36-bit or wider master/  
slave dual-port static RAM. An M/S pin is provided for imple-  
menting 32-/36-bit or wider memory applications without the  
need for separate master and slave devices or additional  
discrete logic. Application areas include interprocessor/multi-  
processor designs, communications status buffering, and  
dual-port video/graphics memory.  
Each port has independent control pins: Chip Enable (CE),  
Read or Write Enable (R/W), and Output Enable (OE). Two  
flags are provided on each port (BUSY and INT). BUSY  
signals that the port is trying to access the same location  
currently being accessed by the other port. The Interrupt Flag  
(INT) permits communication between ports or systems by  
means of a mail box. The semaphores are used to pass a flag,  
or token, from one port to the other to indicate that a shared  
resource is in use. 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  
select (CE) pin.  
neous reads of the same memory location  
• 4K x 16 organization (CY7C024)  
• 4K x 18 organization (CY7C0241)  
• 8K x 16 organization (CY7C025)  
• 8K x 18 organization (CY7C0251)  
• 0.65-micron CMOS for optimum speed/power  
• High-speed access: 15 ns  
• Low operating power: ICC = 150 mA (typ.)  
• Fully asynchronous operation  
• Automatic power-down  
• Expandable data bus to 32/36 bits or more using  
Master/Slave chip select when using more than one  
device  
• On-chip arbitration logic  
• Semaphores included to permit software handshaking  
between ports  
• INT flag for port-to-port communication  
• Separate upper-byte and lower-byte control  
• Pin select for Master or Slave  
• Available in 84-pin Lead (Pb)-free PLCC, 84-pin PLCC,  
100-pin Lead (Pb)-free TQFP, and 100-pin TQFP  
The CY7C024/0241 and CY7C025/0251 are available in  
84-pin Lead (Pb)-free PLCCs, 84-pin PLCCs (CY7C024 and  
CY7C025 only), 100-pin Lead (Pb)-free Thin Quad Plastic  
Flatplack (TQFP) and 100-pin Thin Quad Plastic Flatpack.
