An adjustable voltage reference circuit () that can be adjusted via an external device is disclosed. The circuit is designed to receive, after packaging, a plurality of adjustment inputs (). These inputs are used by an adjustable voltage cell () to produce an adjustment factor. The adjustment factor will then be used by a voltage reference cell () to adjust the reference voltage (Vref).

Circuit and method for a programmable reference voltage

A programmable data latch ( ) is disclosed. The data latch comprises a master latch ( ) operable to load data into the data latch ( ) and a slave latch ( ) operable to receive the data and produce the output ( ) and inverted output of the data latch ( ). Also provided is a plurality of programmable floating gate transistor ( ) wherein the &ldquo;on&rdquo; or &ldquo;off&rdquo; state of the floating gate transistor ( ) is determined by the data loaded into the data latch ( ). A programming voltage supply ( ) is supplied to the floating gate transistors ( ) which increases the threshold voltage of the floating gate transistor ( ) in the &ldquo;on&rdquo; state and produces a programmed transistor. The programmed transistor is operable to set the state of the data latch ( ) upon subsequent use.
