Programmable data device and method therefor |
摘要 |
A programmable data latch (21) is disclosed. The data latch comprises a master latch (34) operable to load data into the data latch (21) and a slave latch (36) operable to receive the data and produce the output (20) and inverted output of the data latch (21). Also provided is a plurality of programmable floating gate transistor (53, 54) wherein the "on" or "off" state of the floating gate transistor (53, 54) is determined by the data loaded into the data latch (21). A programming voltage supply (26) is supplied to the floating gate transistors (53, 54) which increases the threshold voltage of the floating gate transistor (53, 54) in the "on" state and produces a programmed transistor. The programmed transistor is operable to set the state of the data latch (21) upon subsequent use.
