... After the timer circuit in the IC works and creates the period of tE/W, this time circuit completes automatically. And write to the memory cell is made in the period of tE/W, and during this period, other command is not accepted. R/B display = "H" (READY) = command wait status (D0 status) Even after tE/W (Max ...
