Abstract
Fuse data used to configure ancillary circuits used with a non-volatile serial memory core are stored in locations within the memory core. As a first opcode or word is sent on a serial bus to the memory, a logic circuit intercepts the word and generates read fuse enable pulses that fetch the fuse data and configure the ancillary circuits before the last bit of the first command byte arrives. If a read operation is designated, the memory circuits are configured to read. If a write operation is designated, further fuse data is fetched from the memory core to configure ancillary circuits for writing. The fuse data is written to the memory core at the time of circuit manufacture thereby obviating the need for separate storage locations.
