HM621400H Series 4M High Speed SRAM (4-Mword × 1-bit) ADE-203-787D (Z) Rev. 1.0 Sep. 15, 1998 Description The HM621400H 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 HM621400H is packaged in 400-mil 32-pin SOJ for high density surface mounting. Features • Single 5.0 V supply : 5.0 V ± 10 % • Access time 10/12/15 ns (max) • Completely static memory  No clock or timing strobe required • Equal access and cycle times • Directly TTL compatible  All inputs and outputs • Operating current: 200/180/160 mA (max) • TTL standby current: 70/60/50 mA (max) • CMOS standby current: 5 mA (max) : 1.2 mA (max) (L-version) • Data retension current: 0.8 mA (max) (L-version) • Data retension voltage: 2 V (min) (L-version) • Center VCC and VSS type pinout HM621400H Series Ordering Information Type No. HM621400HJP-10 HM621400HJP-12 HM621400HJP-15 HM621400HLJP-10 HM621400HLJP-12 HM621400HLJP-15 Access time 10 ns 12 ns 15 ns 10 ns 12 ns 15 ns Package 400-mil 32-pin plastic SOJ (CP-32DB) Pin Arrangement HM621400HJP/HLJP Series A0 A1 A2 A3 A4 A5 CS VCC VSS Din WE A6 A7 A8 A9 A10 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 (Top view) 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 A21 A20 A19 A18 A17 A16 OE VSS VCC Dout A15 A14 A13 A12 A11 NC 2 HM621400H Series Pin Description Pin name A0 to A21 Din Dout CS OE WE VCC VSS NC Function Address input Data input Data output Chip select Output enable Write enable Power supply Ground No connection Block Diagram (LSB) A2 A18 A8 A12 A17 A3 A7 A6 (MSB) Din Column I/O Column decoder CS Dout Row decoder Memory matrix 256 rows × 64 columns × 256 blocks × 1 bit (4,194,304 bits) Internal voltage generater VCC VSS CS A11 A9 A10 A20 A21 A0 A13 A14 A15 A1 A19 A16 A4 A5 CS WE OE CS (LSB) (MSB) 3 HM621400H Series Operation Table CS H L L L L Note: OE × H L H L ×: H or L WE × H H L L Mode Standby Output disable Read Write Write VCC current I SB , I SB1 I CC I CC I CC I CC Dout High-Z High-Z Dout High-Z High-Z Ref. cycle — — Read cycle (1) to (3) Write cycle (1) Write cycle (2) Absolute Maximum Ratings Parameter Supply voltage relative to VSS Voltage on any pin relative to V SS Power dissipation Operating temperature Storage temperature Storage temperature under bias Symbol VCC VT PT Topr Tstg Tbias Value –0.5 to +7.0 –0.5* to V CC+0.5* 1.0 0 to +70 –55 to +125 –10 to +85 1 2 Unit V V W °C °C °C Notes: 1.

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 HM621400H Series Timing Waveforms Read Timing Waveform (1) (WE = VIH) tRC Address Valid address tAA tACS tOH tCHZ CS tOE OE tOLZ tCLZ Dout High Impedance Valid data tOHZ Read Timing Waveform (2) (WE = VIH, CS = VIL , OE = VIL ) tRC Address tOH Dout Valid address tAA tOH Valid data 8 HM621400H Series Read Timing Waveform (3) (WE = VIH, CS = VIL , OE = VIL )*2 tRC CS tACS tCLZ Dout High Impedance Valid data High Impedance tCHZ Write Timing Waveform (1) (WE Controlled) tWC Address Valid address tAW OE tCW CS*3 tAS WE*3 tOHZ Dout High impedance*5 tDW Din *4 tDH *4 tWP tWR Valid data 9 HM621400H Series Write Timing Waveform (2) (CS Controlled) tWC Address Valid address tCW CS *3 tAW tWP WE *3 tAS tWHZ Dout tOW High impedance*5 tDW Din *4 tDH *4 tWR Valid data 10 HM621400H Series Low VCC Data Retention Characteristics (Ta = 0 to +70°C) This characteristics is guaranteed only for L-version.
