ABSTRACT:
An apparatus includes a nonvolatile memory including a plurality of memory cells, each configured to store data having at least two bits and a control circuit configured to write data to a first memory cell connected to a wordline of the nonvolatile memory and to then write data to a second memory cell that is connected to wordline and shares a bit buffer with the first memory cell.
