  • Patent number: 6496417
    Abstract: A method and an integrated circuit for performing a soft program after erase provides efficient convergence of over-erased floating gate memory cells disposed in bit lines. The soft program is applied to successive subject bit lines. The BLISP method includes selection of a selected bit line and applying the soft program to a subject bit line corresponding to the selected bit line. For integrated circuits having no defective bit lines, the subject bit lines comprise the selected bit lines. The BLISP method is adapted for low current consumption compared to bulk soft programming methods. In some embodiments, the integrated circuit includes defective bit lines. For these integrated circuits, the selection of the selected bit line includes indicating a bit line type corresponding to the selected bit line. The defective bit lines are logically replaced by redundant bit lines so that the soft program is applied to conforming selected bit lines and redundant bit lines corresponding to defective bit lines.

  • Patent number: 6119226
    Abstract: The present invention provides a new memory device for storage of boot code for microprocessors which boot to either the top or bottom of a memory map on power-up. The device includes a memory array, a first block, and decoders. The first block is defined as rows of the memory array designated for storage of data. The decoders decode a memory access requested for the data. The memory access request may be in either one of a top-down or bottom-up address protocol. In another embodiment, an integrated circuit memory includes: a memory array, a decoder, a control, and a logic gate. The decoders decode a memory access request to select a row of memory array. The control has an output for outputting either a bottom-up or a top-down address protocol signal. The logic gate outputs a logical "Exclusive Or" of the control signal and a corresponding bit of the memory access request, whereby a memory request in a bottom-up address protocol is converted to a memory address in a top-down address protocol.
