Abstract:
1. A fuse data storage system comprising: a non-volatile serial memory having a memory core with read related fuse data for configuring ancillary circuits, the read related fuse data stored in a first addressable location and write related fuse data for configuring ancillary circuits, the write related fuse data stored in a second addressable location; a data bus for carrying a serial data stream to the serial memory, the data stream having a succession of data words including a first data words; logic connected to the data bus, the logic for generating fuse enable signals accessing at least the first location in the core containing read related fuse data; a circuit for receiving the read related fuse data and for configuring read control circuits and outputting configuration data; and ancillary circuits responsive to the configuration data and connected to the logic and to the memory core, the ancillary circuits having means for operating the memory core in data reading and writing operations.
