Notes:

1. An initial pause of 200 ms is required after power-up, followed by any 8 RAS cycles.

(Example : RAS-only-refresh) before proper device operation is achieved.

4. This parameter is measured with a load circuit equivalent to 1 TTL load and 50 pF.

outputs achieve the open circuit condition and are not referenced to output voltage

levels.

7. These parameters are referenced to UCAS, LCAS, leading edge in an early write cycle,

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

earlywritecycleandthedataoutwillremainopencircuit(highimpedance)throughout

the cycle is a read modify write cycle and data out will contain data read from the

selected cell; if neither of the above sets of conditions is satisfied, the condition of the

data out (at access time) is indeterminate.

11. These parameters are determined by the falling edge of UCAS or LCAS, whichever is

earlier.

12. These parameters are determined by the rising edge of UCAS or LCAS, whichever is

later.

15. Input levels at the AC testing are 3.0 V/0.5 V.
