HM628511H Series
524288-word x 8-bit High Speed CMOS Static RAM
ADE-203-762(Z) Preliminary Rev. 0.0 Mar. 27, 1997 Description
The HM628511H Series is an asyncronous high speed static RAM organized as 512-k word x 8-bit. It has realized high speed access time by employing CMOS process and high speed circuit designing technology. It is most appropriate for the application which requires high speed, high density memory and wide bit width configuration, such as cache and buffer memory in system. It is packaged in 400-mil 36-pin plastic SOJ.

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, I/O 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. tAS is measured from the latest address transition to the later of CS or WE going low. 7. tWR 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. tCW is measured from the later of CS going low to the the end of write.
