The U62H256A is a static RAM
manufactured using a CMOS pro-
cess technology with the following
operating modes:
- Read
- Standby
- Write
- Data Retention
The memory array is based on a
6-transistor cell.
The circuit is activated by the fal-
ling edge of E. The address and
control inputs open simultaneously.
According to the information of W
and G, the data inputs, or outputs,
are active. In a Read cycle, the
data outputs are activated by the
falling edge of G, afterwards the
data word will be available at the
outputs
DQ0-DQ7.
address change, the data outputs
After
the
go High-Z until the new information
is available. The data outputs have
no preferred state. The Read cycle
is finished by the falling edge of W,
or by the rising edge of E, respec-
tively.
Data retention is guaranteed down
to 2 V. With the exception of E, all
inputs consist of NOR gates, so
that no pull-up/pull-down resistors
are required.
