ABSTRACT:
A current-limited latch circuit is used within a nonvolatile memory integrated circuit for decoding, programming, erase, and other operations. In one implementation, there are a number of latches connected together in parallel between two power supply lines. A current mirroring scheme limits current supplied to the latch. This reduces a difference of the two supplies, positive voltage, ground, or negative voltages, during data changes. The circuit provides smaller device sizes and fast speeds when data changes in the latch, while also providing lower power consumption. The technique provides greater benefits as the voltage difference between the two power supplies is greater.
