FUNCTIONAL DESCRIPTION
INPUT BUFFER
The MTS1512K8C is a high-performance Low Power
CMOS Static Random Access Memory (SRAM),
organized as 512K words by 8-bits wide, containing a
total density of 512K bytes. Memory expansion is easily
achieved through use of the Chip-Select (CS\) and
Output Enable (OE\) control inputs along with the tri-
state output drivers. Writing to the device is
accomplished by driving CS\ and WE\ LOW. Data on
the eight IO pins (IO0-IO7) is then written into the
addressed location specified on the Address Input pins
(A0-A18).

Reading from the MTS1512K8C is accomplished by
driving Chip Select (CS\) and Output Enable (OE\) LOW,
while forcing Write Enable (WE\) HIGH. Under these
stimulus conditions, the contents of the addressed
memory location (A0-A18) will be available on the
Output pins (IO0-IO7).

The MTS1512K8C is placed into an inactive, High-
Impedance state when the device has been de-selected
by driving Chip-Select (CS\) HIGH. The eight Input-
Output lines (IO0-IO7) are also in a High-Impedance
state when the MTS1512K8C is placed into a WRITE
operation by driving Chip-Select (CS\) and Write Enable
(WE\) LOW. This device supports Low Voltage Data
Retention.
