Patent ID: 7345926

Claim:
A flash memory device, comprising: at least one memory array comprised of non-volatile memory cells arranged in rows and columns; a data register, for storing data corresponding to stored states of the memory cells in the at least one memory array; and control circuitry, coupled to the data register, coupled to input/output terminals, and coupled to a plurality of control terminals, for receiving data from the input/output terminals and for presenting data to the input/output terminals, and for controlling the operation of the device in a normal operating mode and in an advanced mode, responsive to control signals received at the control terminals; wherein, in the normal operating mode, the control circuitry presents data words at the input/output terminals responsive to transitions of a first polarity of a read data strobe signal received at a first one of the plurality of control terminals; and wherein, in the advanced operating mode, the control circuitry presents read data strobe signals at the one of the plurality of control terminals, and presents data words at the input/output terminals responsive to transitions of both the first polarity and a second polarity of the read data strobe signal.
