Abstract
A one-chip flash-memory device includes a flash-memory array, a communications unit for analyzing a serial signal applied to the communications unit and for resolving the serial signal into an address, a command, and data in parallel with each other, and a control unit for controlling rewriting, erasing, and reading operations of the flash-memory array in accordance with the address, the command, and the data of the serial signal received by the communications unit. Rewriting and erasing operations may be performed without dismounting the flash-memory from a circuit board. In addition, the area of the circuit board on which the flash-memory is mounted is advantageously reduced.
