Abstract
A programmable current-limited voltage buffer. The programmable current-limited voltage buffer includes at least one current-bias circuit, an inverter, a write-current set control circuit, and an adaptive current limiter. The inverter is coupled to the current-bias circuit and a reference-voltage source, and is configured to couple a row line to either the current-bias circuit, or the reference-voltage source, in response to an input signal. The adaptive current limiter is coupled to the current-bias circuit and to the write-current set control circuit, and is configured to limit current flowing through the memory element in a write operation. An integrated circuit device is also provided, along with a method for current limiting a memory element during switching in an array of memory elements.
