Functional Description
The CY7C106D and CY7C1006D are high-performance
CMOS static RAMs organized as 262,144 words by 4 bits.
Easy memory expansion is provided by an active LOW Chip
Enable (CE), an active LOW Output Enable (OE), and tri-state
drivers. These devices have an automatic power-down feature
that reduces power consumption by more than 65% when the
devices are deselected. The four input and output pins (IO
0
through IO
3
) are placed in a high-impedance state when:
• Deselected (CE HIGH)
• Outputs are disabled (OE HIGH)
• When the write operation is active (CE and WE LOW)
Write to the device by taking Chip Enable (CE) and Write
Enable (WE) inputs LOW. Data on the four IO pins (IO
0
through IO
3
) is then written into the location specified on the
address pins (A
0
through A
17
).
Read from the device 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 appears on the four IO pins.
