ABSTRACT:
A programmable reference voltage generator includes a diode arrangement for generating a reference voltage in response to a control current. An array of memory cells is provided for adjusting the control current, the memory cell array including a plurality of memory cells connected to the diode arrangement through a plurality of current paths. Each of the memory cells is disposed to conduct current when programmed to store a first binary value, and to not conduct current when programmed to store a second binary value. A programming circuit is used to store a selected one of the first and second binary values in each memory cell, thereby causing the reference voltage to assume a selected magnitude.
