  • Auto-tuneable reference circuit for flash EEPROM products
    Patent number: 6826103
    Abstract: Methods and apparatus for trimming a reference circuit. A representative technique includes transmitting a constant signal (e.g., a constant current or voltage). The constant signal is received (e.g., at a device pin or other contact). The constant signal is compared to a reference signal. Variables are obtained for program/erase pulses from a user. The reference circuit signal is adjusted to match the constant signal by sending program/erase pulses to the reference circuit. The program/erase pulses are set based on the variables for program/erase pulses and a result of comparing the constant signal with the reference signal.

  • Self-repair of memory arrays using preallocated redundancy (PAR) architecture
    Publication number: 20040123181
    Abstract: Methods and apparatus for self-repairing non-volatile memory using a PreAllocated Redundancy (PAR) architecture. In a representative embodiment, the non-volatile memory includes a block, a memory subblock, a redundancy subblock having a size equal to the size of the memory subblock, a comparator coupled to the block, a fail latch circuit coupled to the block, and a fuse coupled to the block. The comparator is configured to identify a failure within a particular memory subblock by comparing expected data with read data. The fail latch circuit is configured to determine an address of the particular memory subblock. The fuse is configured to cause the particular memory subblock to be replaced with the redundancy subblock, thereby repairing the non-volatile memory.
