Patent ID: 7092296

Claim:
A nonvolatile memory formed on one semiconductor chip, comprising: a plurality of nonvolatile memory cells, each of which is capable of erasing data by Fowler-Nordheim (FN)-tunnel phenomenon and is capable of storing data by FN-tunnel phenomenon; and a plurality of terminals including an address terminal used for inputting an address information for selecting first nonvolatile memory cells of said plurality of nonvolatile memory cells, a serial clock terminal used for inputting clock pulses, and a data terminal used for inputting data for storing into said first nonvolatile memory cells in response to said clock pulses, wherein said nonvolatile memory is adapted to receiving data for storing into said first nonvolatile memory cells after receiving said address information, wherein said nonvolatile memory is capable of performing a program operation for storing 512 byte data to said first nonvolatile memory cells, and wherein said nonvolatile memory is capable of performing an erase operation for erasing data stored in said first nonvolatile memory cells.
