The

Port Saver memories need no serial ports or spe-

cial hardware and connect to the processor memory bus.

Replacing bytewide data memory, the

Port Saver uses

bytewide memory control functions, takes a fraction of

the board space and consumes much less power.

Replacing serial memories, the

Port Saver provides all

the serial beneﬁts, such as low cost, low power, low volt-

age, and small package size while releasing I/Os for

more important uses.

The

Port Saver memory outputs data within 25ns of an

active read signal. This is less than the read access time

of most hosts and provides “no-wait-state” operation.

This prevents bottlenecks on the bus. With rates to 10

MHz, the

Port Saver supplies data faster than required

by most host read cycle speciﬁcations. This eliminates

the need for software NOPs.

The

Port Saver memories communicate over one line of

the data bus using a sequence of standard bus read and

write operations. This “bit serial” interface allows the

Port Saver to work well in 8-bit, 16 bit, 32-bit, and 64-bit

systems.

A Write Protect (WP) pin prevents inadvertent writes to

the memory.

Xicor EEPROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data reten-

tion is greater than 100 years.
