HM62W1400H Series 4M High Speed SRAM (4-Mword × 1-bit) ADE-203-773E (Z) Rev. 2.0 Nov. 11, 1998 Description The HM62W1400H is a 4-Mbit high speed static RAM organized 4-Mword × 1-bit. It has realized high speed access time by employing CMOS process (4-transistor + 2-poly resistor memory cell)and high speed circuit designing technology. It is most appropriate for the application which requires high speed and high density memory, such as cache and buffer memory in system. The HM62W1400H is packaged in 400-mil 32-pin SOJ and 400-mil 32-pin TSOP II for high density surface mounting.

Transition is measured ±200 mV from steady voltage with Load (B). This parameter is sampled and not 100% tested. 2. Address should be valid prior to or coincident with CS transition low. 3. WE and/or CS must be high during address transition time. 4. if CS and OE are low during this period, Dout pins are in the output state. Then, the data input signals of opposite phase to the outputs must not be applied to them. 5. If the CS low transition occurs simultaneously with the WE low transition or after the WE transition, output remains a high impedance state. 6. t AS is measured from the latest address transition to the later of CS or WE going low. 7. t WR is measured from the earlier of CS or WE going high to the first address transition. 8. A write occurs during the overlap of a low CS and a low WE. A write begins at the latest transition among CS going low and WE going low. A write ends at the earliest transition among CS going high and WE going high. tWP is measured from the beginnig of write to the end of write. 9. t CW is measured from the later of CS going low to the the end of write. 7 HM62W1400H Series Timing Waveforms Read Timing Waveform (1) (WE = VIH) tRC Address Valid address tOH tAA tACS tCHZ CS tOE tOHZ OE tOLZ tCLZ Dout High Impedance Valid data Read Timing Waveform (2) (WE = VIH, CS = VIL , OE = VIL ) tRC Address Valid address tAA tOH tOH Dout 8 Valid data HM62W1400H Series Read Timing Waveform (3) (WE = VIH, CS = VIL , OE = VIL )*2 tRC CS tACS tCHZ tCLZ Dout High Impedance Valid data High Impedance Write Timing Waveform (1) (WE Controlled) tWC Valid address Address tWR tAW OE tCW CS*3 tAS tWP WE*3 tOHZ High impedance*5 Dout tDW Din *4 tDH Valid data *4 9 HM62W1400H Series Write Timing Waveform (2) (CS Controlled) tWC Valid address Address tWR tCW CS *3 tAW tWP WE *3 tAS tWHZ tOW High impedance*5 Dout tDW Din 10 *4 tDH Valid data *4 HM62W1400H Series Low VCC Data Retention Characteristics (Ta = 0 to +70°C) This characteristics is guaranteed only for L-version.
