U62H64
The U62H64 is a static RAM manu-
factured using a CMOS process
technology with the following ope-
rating modes:
- Read
- Standby
- Write
- Data Retention
The memory array is based on a
6-transistor cell.
The circuit is activated by the rising
edge of E2 (at E1 = L), or the falling
edge of E1 (at E2 = H). 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 read will be available at
the outputs DQ0 - DQ7. After the
address change, the data outputs
go High-Z until the new read infor-
mation is available. The data out-
puts have no preferred state. If the
memory is driven by CMOS levels
in the active state, and if there is no
change of the address, data input
and control signals W or G, the
operating current (at I
O
= 0 mA)
drops to the value of the operating
current in the Standby mode. The
Read cycle is finished by the falling
edge of E2 or W, or by the rising
edge of E1, respectively.
Data retention is guaranteed down
to 2 V.
With the exception of E1 and E2,
all inputs consist of NOR gates, so
that no pull-up/pull-down resistors
are required. This gate circuit
allows to achieve low power
standby requirements by activation
with TTL-levels too.
