HMS1M32M8G, HMS1M32Z8
GENERAL DESCRIPTION
The HMS1M32M8G/Z8 is a high-speed static random access memory (SRAM) module containing 1,048,576
words organized in a x32-bit configuration. The module consists of eight 1M x 4 SRAMs mounted on a 72-pin,
double-sided, FR4-printed circuit board.
PD0 to PD3 identify the module’s density allowing interchangeable use of alternate density, industry- standard
modules. Eight chip enable inputs, (/CE1, /CE2, /CE3 and /CE4) are used to enable the module’s 4 bytes
independently. Output enable(/OE) and write enable(/WE) can set the memory input and output.
Data is written into the SRAM memory when write enable (/WE) and chip enable (/CE) inputs are both LOW.
Reading is accomplished when /WE remains HIGH and /CE and output enable (/OE) are LOW.
For reliability, this SRAM module is designed as multiple power and ground pin. All module components may be
powered from a single +5V DC power supply and all inputs and outputs are fully TTL-compatible.

Notes (Read Cycle)
1. /WE is high for read cycle.
2. All read cycle timing is referenced from the last valid address to first transition address.
3. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit condition and are not referenced to VOH
or VOL levels.
4. At any given temperature and voltage condition, tHZ (max.) is less than tLZ (min.) both for a given device and from device
to device.
5. Transition is measured ± 200mV from steady state voltage with Load (B). This parameter is sampled and not 100%
tested.
6. Device is continuously selected with /CE = VIL.
7. Address valid prior to coincident with /CE transition low.

Notes(Write Cycle)
1. All write cycle timing is referenced from the last valid address to the first transition address.
2. A write occurs during the overlap of a low /CE and a low /WE. A write begins at the latest transition among
/CE going low and /WE going low: A write ends at the earliest transition among /CE going high and /WE going high.
tWP is measured from the beginning of write to the end of write.
3. tCW is measured from the later of /CE going low to the end of write.
4. tAS is measured from the address valid to the beginning of wirte.
5. tWR is measured from the end of write to the address change. tWR applied in case a write ends as /CE, or /WE going high.
6. If /OE,/CE and /WE are in the read mode during this period, the I/O pins are in the output low-Z state. Inputs of
opposite phase of the output must not be applied because bus contention can occur.
7. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and
write cycle.
8. If /CE goes low simultaneously with /WE going low or after /WE going low, the outputs remain high impedance state.
9. DOUT is the read data of the new address.
10. When /CE is low: I/O pins are in the output state. The input signals in the opposite phase leading to the output
should not be applied.
