Abstract: Disclosed herein are related to a system and a method of extending a lifetime of a memory cell. In one aspect, a memory controller applies a first pulse having a first amplitude to the memory cell to write input data to the memory cell. In one aspect, the memory controller applies a second pulse having a second amplitude larger than the first amplitude to the memory cell to extend a lifetime of the memory cell. The memory cell may include a resistive memory device or a phase change random access memory device. In one aspect, the memory controller applies the second pulse to the memory cell to repair the memory cell in response to determining that the memory cell has failed. In one aspect, the memory controller periodically applies the second pulse to the memory cell to extend the lifetime of the memory cell before the memory cell fails.

Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.
