Functional Description
The
high-speed CMOS 1K by 8 dual-port static RAMs. Two ports
are provided permitting independent access to any location in
memory. The CY7C130/ CY7C131 can be utilized as either a
standalone 8-bit dual-port static RAM or as a master dual-port
RAM in conjunction with the CY7C140/CY7C141 slave du-
al-port device in systems requiring 16-bit or greater word
widths. It is the solution to applications requiring shared or
buffered data, such as cache memory for DSP, bit-slice, or
multiprocessor designs.
Each port has independent control pins; chip enable (CE),
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 ac-
cessed by the other port. INT is an interrupt flag indicating that
data has been placed in a unique location (3FF for the left port
and 3FE for the right port). An automatic power-down feature
is controlled independently on each port by the chip enable
(CE) pins.
The CY7C130 and CY7C140 are available in 48-pin DIP. The
CY7C131 and CY7C141 are available in 52-pin PLCC and
PQFP.
