Abstract
Disclosed is a nonvolatile memory system including at least one nonvolatile memory each having a plurality of nonvolatile memory cells and a buffer memory; and a control device coupled to the nonvolatile memory. The control device is enabled to receive external data and to store the data in the nonvolatile memory, and the nonvolatile memory is capable of performing at least a program operation and an erase operation. Moreover, the control device is enabled to receive external data while the nonvolatile memory is operating in the erase operation. Also, the buffer memory is capable of receiving a unit of data, in the program operation, equal to the data length of data to be stored at one time of the program operation, the data length being more than 1 byte.
