DISTRIBUTED CASCODE CURRENT SOURCE FOR RRAM SET CURRENT LIMITATION

摘要

In one example, a current limited device is coupled between a source line of a memory cell array and a supply voltage, and configured to operate in a constant current mode during an access operation of a memory cell.

主权项

1. An apparatus, comprising:
a memory element of a memory cell of a memory cell array, wherein the memory element is coupled to a source line of the memory cell array through a word line select transistor; and a current limiting device coupled between the source line and a supply voltage, the current limiting device to operate in a constant current mode during an access operation of the memory cell.
