8/14

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.

This parameter is measured with a load circuit equivalent to 2 TTL load and 100pF.

write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle.

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, then the condition of the data out (at access time)

is indeterminate.

10. These parameters are referenced to the

UCAS and LCAS, leading edges in an early write cycle,

and to the

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

11. These parameters are determined by the falling edge of either

UCAS or LCAS, whichever is

earlier.

12. These parameters are determined by the rising edge of either

UCAS or LCAS, whichever is later.

UCAS and LCAS are high.
