CY7C106  
CY7C1006  
256K x 4 Static RAM  
an active LOW output enable (OE), and three-state drivers.  
These devices have an automatic power-down feature that re-  
duces power consumption by more than 65% when the devic-  
es are deselected.  
Features  
• High speed  
— tAA = 12 ns  
• CMOS for optimum speed/power  
• Low active power  
Writing to the devices 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 speci-  
fied on the address pins (A0 through A17).  
— 910 mW  
• Low standby power  
— 275 mW  
Reading from the devices is accomplished by taking chip en-  
able (CE) and output enable (OE) LOW while forcing write en-  
able (WE) HIGH. Under these conditions, the contents of the  
memory location specified by the address pins will appear on  
the four I/O pins.  
• 2.0V data retention (optional)  
100 µW  
Automatic power-down when deselected  
TTL-compatible inputs and outputs  
The four input/output pins (I/O0 through I/O3) are placed in a  
high-impedance state when the devices are deselected (CE  
HIGH), the outputs are disabled (OE HIGH), or during a write  
operation (CE and WE LOW).  
Functional Description  
The CY7C106 and CY7C1006 are high-performance CMOS  
static RAMs organized as 262,144 words by 4 bits. Easy mem-  
ory expansion is provided by an active LOW chip enable (CE),  
The CY7C106 is available in a standard 400-mil-wide SOJ; the  
CY7C1006 is available in a standard 300-mil-wide SOJ.
