Features
Description
• This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of
Paragraph 1.2.1.
The HM-6504/883 is a 4096 x 1 static CMOS RAM
fabricated using self-aligned silicon gate technology. The
device utilizes synchronous circuitry to achieve high performance and low power operation.
• Low Power Standby . . . . . . . . . . . . . . . . . . . 125µW Max
• Low Power Operation . . . . . . . . . . . . . 35mW/MHz Max
• Data Retention . . . . . . . . . . . . . . . . . . . . . . . at 2.0V Min
• TTL Compatible Input/Output
• Three-State Output
• Standard JEDEC Pinout
• Fast Access Time. . . . . . . . . . . . . . . . . . 120/200ns Max
On-chip latches are provided for addresses, data input and
data output allowing efficient interfacing with microprocessor
systems. The data output can be forced to a high impedance
state for use in expanded memory arrays.
Gated inputs allow lower operating current and also eliminate the need for pull up or pull down resistors. The
HM-6504/883 is a fully static RAM and may be maintained in
any state for an indefinite period of time.
Data retention supply voltage and supply current are guaranteed over temperature.

The address information is latched in the on-chip registers
on the falling edge of E (T = 0). Minimum address set up and
hold time requirements must be met. After the required hold
time, the addresses may change state without affecting
device operation. During time (T = 1) the output becomes
enabled but the data is not valid until during time (T = 2). W
must remain high for the read cycle. After the output data
has been read, E may return high (T = 3). This will disable
the output buffer and all input, and ready the RAM for the
next memory cycle (T = 4).

The early write cycle is the only cycle where the output is
guaranteed not to become active. On the falling edge of E
(T = 0), the addresses, the write signal, and the data input
are latched in on-chip registers. The logic value of W at the
time E falls determines the state of the output buffer for that
cycle. Since W is low when E falls, the output buffer is
latched into the high impedance state and will remain in that
FUNCTION
state until E returns high (T = 2). For this cycle, the data
input is latched by E going low; therefore, data set up and
hold times should be referenced to E. When E (T = 2)
returns to the high state, the output buffer and all inputs are
disabled and all signals are unlatched. The device is now
ready for the next cycle.

The late write cycle is a cross between the early write cycle
and the read-modify-write cycle.
Recall that in the early write, the output is guaranteed to
remain high impedance, and in the read-modify-write, the
output is guaranteed valid at access time. The late write is
FUNCTION
between these two cases. With this cycle the output may
become active, and may become valid data, or may remain
active but undefined. Valid data is written into the RAM if
data setup, data hold, write setup and write pulse widths are
observed.
