ABSTRACT
Efficient information storage and processing mainly depends on the storage capacity and read/write speed of the memory. At present various memory technologies, volatile (SRAM, DRAM)/non-volatile (Flash, hard disk), combined do this task and demands of high storage density and speed are met with the miniaturization of the memory cells until now. However, the semiconductor manufacturing industry is in the hunt for an endurable technology that involves features of non-volatility of Flash, speed of SRAM and the great scalability of DRAM to meet anticipated future demands. The article thus presents current semiconductor memories with emerging memory concepts to realize a novel “universal memory” that has all the virtues of different existing memories. Such a memory can bring simplicity to computer architecture and eventually improve the computational performance of mobile and stationary systems. Additionally, the non-volatility greatly reduces energy consumption and hence environmentally benign.
