= 1.4V.
13. At any given temperature and voltage condition for any given device, t

15. The internal write time of the memory is defined by the overlap of CS LOW and R/W LOW. Both signals must be low to initiate a write and either signal can
terminate a write by going high. The data input set-up and hold timing should be referenced to the rising edge of the signal that terminates the write.
