SOFT ERROR-RESILIENT LATCH
Abstract:
A latch is provided. The latch includes a plurality of storage nodes including a plurality of data storage nodes configured to store a data bit having one of two states and a plurality of complementary data storage nodes configured to store a complement of the data bit. The latch includes a plurality of supply voltage multi-dependency stages respectively corresponding to the plurality of storage nodes. Each supply voltage multi-dependency stage has an output coupled to a storage node and at least two control inputs respectively coupled to at least two other storage nodes of the plurality of storage nodes. The supply voltage multi-dependency stage is configured to cause a state of the data bit stored in the storage node to change from a first state to a second state in response a change in both states of two data bits respectively stored in the at least two other storage nodes.
