Abstract:
A nonvolatile memory system comprising:a nonvolatile memory including a plurality of nonvolatile memory cells and a buffer memory; and a control device coupled to said nonvolatile memory, wherein said control device is enabled to receive data from outside said nonvolatile memory system and to apply said data to said nonvolatile memory, wherein said nonvolatile memory is enabled to operate at least a program operation and an erase operation, wherein in said program operation, said nonvolatile memory receives said data from said control device, stores said data to said buffer memory and stores said data in said buffer memory to ones of said nonvolatile memory cells, wherein in said erase operation, said nonvolatile memory erases data stored in ones of said nonvolatile memory cells, wherein said control device is enabled to receive data from outside of said nonvolatile memory system, while said nonvolatile memory is operating in said erase operation, and wherein said buffer memory has a data storing capacity enabling the receiving of a unit of data of a length equal to the data length of said data to be stored at one time of said program operation, said data length being more than 1 byte.
