Patent ID: 7079411

Claim:
A ferroelectric nonvolatile code data output device, comprising: a code bus command processing unit for activating a decoder enable signal and a code selecting enable signal when a code data output command is applied; a code bus decoder unit for selectively activating a selecting signal in response to a decoder input signal when the decoder enable signal is activated; a function block unit, which comprises a plurality of function blocks for storing nonvolatile code data required in an operation of a chip, for outputting the code data in response to the selecting signal; a code bus, which is shared by the function blocks, for transmitting the code data applied by the function block unit; a data buffer for temporarily storing data inputted and outputted through an input/output port; and a data selecting unit for selectively connecting the data buffer to one of a data bus and the code bus which transmit data of a memory cell array in response to the code selecting enable signal.
