HY62WT08081E Series
DESCRIPTION
The HY62WT08081E is a high-speed, low power and 32,786 X 8-bits CMOS Static Random Access Memory fabricated using Hynix's high performance CMOS process technology. It is suitable for use in low voltage operation and battery back-up application. This device has a data retention mode that guarantees data to remain valid at the minimum power supply voltage of 2.0 volt.

Note(READ CYCLE): 1. tCHZ and tOHZ are defined as the time at which the outputs achieve the open circuit conditions and arenot referenced to output voltage levels. 2. At any given temperature and voltage condition, tCHZ max. is less than tCLZ min. both for a given device and from device to device. 3. /WE is high for the read cycle.

Notes(WRITE CYCLE): 1. 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 beginning of write to the end of write. 2. tCW is measured from the later of /CS going low to the end of write . 3. tAS is measured from the address valid to the beginning of write. 4. tWR is measured from the end of write to the address change. tWR is applied in case a write ends as /CS, or /WE going high. 5. If /OE and /WE are in the read mode during this period, and the I/O pins are in the output low-Z state, input of opposite phase of the output must not be applied because bus contention can occur. 6. If /CS goes low simultaneously with /WE going low, or after /WE going low, the outputs remain in high impedance state. 7. DOUT is the same phase of the latest written data in this write cycle. 8. DOUT is the read data of the new address.
