18 Mb DDR II SRAM Burst of 4 Commercial Temperature Range
DC Electrical Characteristics Over the Operating Temperature and
Supply Voltage Range
(V

= 1.8 ± 100mV, V
DDQ
= 1.4V to 1.9V)
NOTES:
1. Operating Current is measured at 100% bus utilization.
2. Standby Current is only after all pending read and write burst operations are completed.
3. Outputs are impedance-controlled. IOH = -(VDDQ/2)/(RQ/5) and is guaranteed by device characterization for 175
< RQ < 350
.
This
parameter is tested at RQ = 250
,
which gives a nomnal 50
output impedance.
4. Outputs are impedance-controlled. IOL = (VDDQ/2)/(RQ/5) and is guaranteed by device characterization for 175
< RQ < 350
.
This
parameter is tested at RQ = 250
,
which gives a nomnal 50
output impedance.
5. This measurement is taken to ensure that the output has the capability of pulling to the VDDQ rail, and is not intended to be used as an impedance
measurement point.
6. This measurement is taken to ensure that the output has the capability of pulling to Vss, and is not intended to be used as an impedance
measurement point.
7. Programmable Impedance Mode.
