The U630H16 has two separate
modes of operation: SRAM mode
and non-volatile mode, determined
by the state of the NE pad.
In SRAM mode, the memory ope-
rates as an ordinary static RAM. In
non-volatile operation, data is
transferred in parallel from SRAM
to EEPROM or from EEPROM to
SRAM. In this mode SRAM
functions are disabled.
The U630H16 is a fast static RAM
(25, 35, 45 ns), with a non-volatile
electrically erasable PROM
(EEPROM) element incorporated
in each static memory cell. The
SRAM can be read and written an
unlimited number of times, while
independent non-volatile data resi-
des in EEPROM. Data transfers
from the SRAM to the EEPROM
(the STORE operation), or from the
EEPROM to the SRAM (the
RECALL operation) are initiated
through the state of the NE pad.
The U630H16 combines the high
performance and ease of use of a
fast SRAM with non-volatile data
integrity.
Once a STORE cycle is initiated,
further input or output are disabled
until the cycle is completed.
Internally, RECALL is a two step
procedure. First, the SRAM data is
cleared and second, the non-vola-
tile information is transferred into
the SRAM cells.
The RECALL operation in no way
alters the data in the EEPROM
cells. The non-volatile data can be
recalled an unlimited number of
times.
The chips are tested with a
restricted wafer probe program
at room temperature only. Unte-
sted parameters are marked with
a number sign (#).
