A non-volatile memory device comprises an interface circuit for receiving a plurality of signals. The plurality of signals provides multiplexed address and data and command signals in a serial format. An input buffer stores a plurality of the plurality of signals received in serial format and reconstitutes the address, data and command signals, and has an output. A command circuit receives the output of the input buffer and stores the command signals therefrom. An address circuit receives the output of the input buffer and stores the address signals therefrom. A data buffer circuit receives the output of the input buffer and stores the data signals therefrom. An array of non-volatile memory cells stores data from and provides data to the data buffer in response to address signals from the address decoder. A state machine is connected to the command circuit and controls the array of non-volatile memory cells. An output buffer receives data from the data buffer circuit and provides data to the interface circuit.

Non-volatile memory device having high speed serial interface

A reprogrammable fuse has a pair of non-volatile memory cells differentially programmed. The pair of non-volatile memory cells are connected to a pair of bitlines and through a pair of switches to a precharging voltage. The switches are controlled by a precharging and equalization signal, which when activated, serves to precharge the bitlines. The charged bitlines are then connected to the pair of differentially programmed non-volatile memory cells and one of the bitlines is discharged faster than the other. The resultant output is taken from one of the bitlines.
