ABSTRACT:
A reference circuit which is particularly useful in combination with a memory array in which data transistors are arranged in rows and columns and in which the conduction paths of the data transistors along each column are connected in series between a common ground line and a bit line forming a stack. A problem exists in that the signal current flowing in a stack varies as a function of the position of a selected data transistor along the stack and of the information stored in the other data transistors of the stack. The reference circuit includes means for generating a different reference current corresponding to each row of data transistors along the stacks, where each reference current mirrors and tracks a particular signal condition of the data transistors being sensed in its corresponding row.
