046B  
CY7C1046B  
1M x 4 Static RAM  
sion is provided by an active LOW Chip Enable (CE), an active  
LOW Output Enable (OE), and three-state drivers. Writing to  
the device is accomplished by taking Chip Enable (CE) and  
Write Enable (WE) inputs LOW. Data on the four I/O pins (I/O0  
through I/O3) is then written into the location specified on the  
address pins (A0 through A19).  
Features  
• High speed  
— tAA = 12 ns  
• Low active power  
— 935 mW (max.)  
Reading from the device is accomplished by taking Chip  
Enable (CE) and Output Enable (OE) LOW while forcing Write  
Enable (WE) HIGH. Under these conditions, the contents of  
the memory location specified by the address pins will appear  
on the I/O pins.  
• Low CMOS standby power (L version)  
— 2.75 mW (max.)  
2.0V Data Retention (400 µW at 2.0V retention)  
Automatic power-down when deselected  
TTL-compatible inputs and outputs  
Easy memory expansion with CE and OE features  
The four input/output pins (I/O0 through I/O3) are placed in a  
high-impedance state when the device is deselected (CE  
HIGH), the outputs are disabled (OE HIGH), or during a write  
operation (CE LOW, and WE LOW).  
Functional Description  
The CY7C1046B is available in a standard 400-mil-wide  
32-pin SOJ package with center power and ground (revolu-  
tionary) pinout.  
The CY7C1046B is a high-performance CMOS static RAM or-  
ganized as 1,048,576 words by 4 bits. Easy memory expan-
