HY64LD16162M Series
1M x 16 bit Low Low Power 1T/1C SRAM
DESCRIPTION
FEATURES
The HY64LD16162M is a 16Mbit 1T/1C SRAM
featured by high-speed operation and super low
power consumption. The HY64LD16162M adopts
one transistor memory cell and is organized as
1,048,576 words by 16bits. The HY64LD16162M
operates in the extended range of temperature and
supports a wide operating voltage range. The
HY64LD16162M also supports the deep power
down mode for a super low standby current. The
HY64LD16162M delivers the high-density low
power SRAM capability to the high-speed low power
system.
• CMOS Process Technology
• 1M x 16 bit Organization
• TTL compatible and Tri-state outputs
• Deep Power Down : Memory cell data hold invalid
• Standard pin configuration : 48-FBGA
• Data mask function by /LB, /UB

Notes :
1. Read Cycle occurs whenever a high on the /WE and /OE is low, while /UB and/or /LB and /CS1 and CS2 are in active status.
2. /OE = VIL
3. tCHZ, tBHZ and tOHZ are defined as the time at which the outputs achieve the high impedance state and tOLZ,tBLZ and tCLZ
are defined as the time at which the outputs achieve the low impedance state.
These are not referenced to output voltage levels.
4. /CS1 in high for the standby, low for active.
/UB and /LB in high for the standby, low for active.

Notes :
1. A write occurs during the overlap of low /CS1, low /WE and low /UB and/or /LB.
2. tWR is measured from the earlier of /CS1, /LB, /UB, or /WE going high to the end of write cycle.
3. During this period, I/O pins are in the output state so that the input signals of opposite phase to the output must not be applied.
4. If the /CS1, /LB and /UB low transition occur simultaneously with the /WE low transition or after the
/WE transition, outputs remain in a high impedance state.
5. /OE is continuously low (/OE=VIL)
6. Q(data out) is the invalid data.
7. Q(data out) is the read data of the next address.
8. tWHZ is defined as the time at which the outputs achieve the high impedance state.
It is not referenced to output voltage levels.
9. /CS1 in high for the standby, low for active. /UB and /LB in high for the standby, low for active.
10. Do not input data to the I/O pins while they are in the output state.

AVOID TIMING
Hynix 1T/1C SRAM has a timing which is not supported at read operation. If your system has multiple
invalid address signal shorter than tRC during over 10us at read operation which showed in abnormal
timing, Hynix 1T/1C SRAM needs a normal read timing at least during 10us which showed in avoidable
timing(1) or toggle the /CS1 to high(≥tRC) one time at least which showed in avoidable timing(2)
