Notes:

1. A start-up delay of 200

µs is required after power-up, followed by a minimum of eight

initialization cycles (RAS-only refresh or CAS before RAS refresh) before proper device

operation is achieved.

4. This parameter is measured with a load circuit equivalent to 2 TTL loads and 50 pF.

circuit condition and are not referenced to output voltage levels.

the cycle is an early write cycle and the data out will remain open circuit (high

cycle and data out will contain data read from the selected cell; if neither of the above

sets of conditions is satisfied, then the condition of the data out (at access time) is

indeterminate.

10. These parameters are referenced to the CAS leading edge in an early write cycle, and

to the WE leading edge in an OE control write cycle, or a read modify write cycle.
