Abstract
An area efficient readable and resettable configuration memory latch maintains latch data integrity through read and write operations and includes a non-terminated inout bit line (BL). During write operations, enabled by a Word Line Write (WLW) signal, the non-terminated inout BL drives data to be written, while, during read operations, enabled by a Word Line Read (WLR) signal, the state of the BL is indicative of a data stored in the latch. A pull-down network is activated when the WLR signal is asserted and the stored data is logic one and, when activated, operates to pull down the BL to logic zero; the pull-down network is inactive otherwise. A weak pull-up operates to pull up the BL when the pull-down network is inactive. A sensing block is configured to sense the state of the BL when the WLR signal and a read enable signal are both asserted.
