HAN BIT SRAM MODULE 768KBit (32K x 24-Bit) Part No.
HMS3224M3/Z3
HMS3224M3, HMS3224Z3
GENERAL DESCRIPTION
The HMS3224M3/Z3 is a high-speed static random access memory (SRAM) module containing 32,768 words organized in a x24-bit configuration. The module consists of three 32K x 8 SRAMs mounted on a 56-pin, singlesided, FR4-printed circuit board. Writing to the device is accomplished when the chip enable (/CE) and write enable(/WE) inputs are both LOW. Data on the input/output pins (DQ0 through DQ23) of the device is written into the memory location specified on the address pins (A0 through A14). Reading the device is accomplished by taking the chip enable (/CE) and output enable(/OE) LOW while write enable(/WE) remains HIGH. Under these conditions, the contents of the memory location specified on the address pins will appear on the input/output pins. The input/output pins remains in a high-impedance state unless the module is selected, outputs are enabled, and write enable is HIGH.

Notes (Read Cycle)
1. /WE is high for read cycle. 2. All read cycle timing is referenced from the last valid address to the first transition address. 3. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit condition 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 write. 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.
