Abstract

A digital voltage shifter 101 is provided which includes an input buffer 200 having an input for receiving data logic high signals at a first voltage, a true output and a complementary output. A static random access memory cell 220 is also included which operates in response to a voltage supply providing a second voltage differing from the first voltage and having a first input coupled to the true output of the input buffer and a second input coupled to the complementary output of the input buffer. An output driver 230 is further included which operates in response to the second supply voltage and is coupled to an output of the memory cell, the output driver outputting the received logic signals at the second voltage.
