General Description
nous, pipelined burst SRAM employs high-speed, low-
power CMOS designs using an advanced 6T CMOS
process.
(double data rate) ports to access the memory array.
The read port has dedicated data outputs to support
READ operations. The write port has dedicated data
inputs to support WRITE operations. This architecture
eliminates the need for high-speed bus turnaround.
Access to each port is accomplished using a common
address bus. Addresses for reads and writes are latched
on alternate rising edges of the K clock. Each address
location is associated with four words that burst
sequentially into or out of the device. Since data can be
transferred into and out of the device on every rising
edge of both clocks (K, and K# and C and C#) memory
bandwidth is maximized and system design is simpli-
fied by eliminating bus turnarounds.
