ABSTRACT:
A nonvolatile memory and a method for controlling the nonvolatile memory to switch between first and second data widths are described. The nonvolatile memory includes a first memory array, a second memory array, a first plurality of data pads, and a second plurality of data pads. A data width control circuit selectively couples the first and second plurality of data pads to the first and second memory arrays. A data width configuration cell is provided for configuring data width of the nonvolatile memory. A data width select circuit controls the data width control circuit to selectively couple the first and second plurality of data pads to the first and second memory arrays under the control of the data width configuration cell. When the data width configuration cell is in a first state, the first and second memory arrays are coupled to the first and second plurality of data pads such that the nonvolatile memory has a first data width. When the data width configuration cell is in a second state, the first and second memory arrays are coupled to the first plurality of data pads such that the nonvolatile memory has a second data width.
