/2 -0.5) ns has to be added to this parameter.
6. Rated at 1.5V

-1) ns has to be added to this parameter.
8. Any time that the refresh Period has been exceeded, a minimum of two Auto (CBR) Refresh commands must be
given to “wake-up” the device.
9. Self Refresh Exit is a synchronous operation and begins on the 2nd positive clock edge after CKE returns high.
Self Refresh Exit is not complete until a time period equal to t
RC
is satisfied once the Self Refresh Exit command
is registered.
Referenced to the time which the output achieves the open circuit condition, not to output voltage levels.
