ABSTRACT:
A memory chip having a multiple input/output system enables a memory to have a .times.n, .times.2n or .times.4n I/O system through a simple fuse mask process by using a single memory chip and reduces the consumption of a cell current while having a memory capacity which is the same as in the .times.n or .times.2n I/O system of the conventional art. The multiple input/output memory chip according to the present invention includes a block selecting unit for receiving a source voltage or a column address lowest bit and thereby selectively activating a first block selection signal or a second block selection signal, a column control unit for receiving a source voltage or a column address lowest bit and thereby selectively activating a first column control signal or a second column control signal, a first bank for simultaneously reading or writing n-bit or 2n-bit data in accordance with the first or second column control signal and the first block selection signal, a second bank for simultaneously reading or writing n-bit or 2n-bit data in accordance with the first or second column control signal and the second block selection signal, and a data bus which is connected with first to third fuses and thereby dividable up to four parts.
