Abstract:
In certain embodiments, the present invention is a word-line driver for an address decoder that decodes a multi-bit address to enable access to a row of circuit elements such as memory cells in a block of memory implemented in a dedicated memory device or as part of a larger device, such as an FPGA. The word-line driver has a feed-back latch for each word-line that ensures that the word-line is not energized when that word-line is not selected for access. By controlling the feed-back latch using a decoded address bit value rather than a pre-charged enable signal as do some prior-art dynamic word-line drivers, the word-line driver prevents undesirable energizing of multiple word-lines. The word-line driver can be implemented using less layout area and less power than some analogous prior-art static word-line drivers.
