Description
The PDM34089 is a 2,097,152 bit synchronous ran-
dom access memory organized as 65,536 x 32 bits. It
is designed with burst mode capability and interface
controls to provide high-performance in second
level cache designs for x86, Pentium, 680x0, and
PowerPC microprocessors. Addresses, write data
and all control signals except output enable are con-
trolled through positive edge-triggered registers.
Write cycles are self-timed and are also initiated by
the rising edge of the clock. Controls are provided to
allow burst reads and writes of up to four words in
length. A 2-bit burst address counter controls the
two least-significant bits of the address during burst
reads and writes. The burst address counter selec-
tively uses the 2-bit counting scheme required by the
x86 and Pentium or 680x0 and PowerPC micropro-
cessors as controlled by the mode pin. Individual
write strobes provide byte write for the four 8-bit
bytes of data. An asynchronous output enable sim-
plifies interface to high-speed buses.
