DESCRIPTION:
The IDT7014 is an extremely high-speed 4K x 9 Dual-Port
Static RAM designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself
to high-speed applications which do not need on-chip arbitra-
tion to manage simultaneous access.
The IDT7014 provides two independent ports with separate
control, address, and I/O pins that permit independent,
asynchronous access for reads or writes to any location in
memory. See functional description.
The IDT7014 utilitizes a 9-bit wide data path to allow for
parity at the user's option. This feature is especially useful in
data communication applications where it is necessary to use
a parity bit for transmission/reception error checking.
Fabricated using IDT’s high-performance technology, the
IDT7014 Dual-Ports typically operate on only 900mW of
power at maximum access times as fast as 12ns.
The IDT7014 is packaged in a 52-pin PLCC and a 64-pin
thin plastic quad flatpack (TQFP).
