MEMRISTORS

Flash memory concept nowadays is in active discussion since researchers are looking at cost effective components. Currently flash memory commands the vast majority of the multibillion dollar non-volatile memory market, but experts agree that Flash memory feature sizes may not continue to scale well into the near future. As a result, most big players  in the market are researching potential alternatives. Memristors are no doubt are the superlative replacement for flash memories. Memristors or resistive switching memories(RRAM) are specially synthesized materials whose resistivity can be electrically switched between high and low conductive states. RRAM has superior intrinsic scaling characteristics compared to the charge-based Flash devices, and potentially small cell size (enabling dense crossbar RRAM arrays using vertical diode selecting elements).
