FUNCTIONAL DESCRIPTION
The MTS1512K8C is a high-performance 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.
