The embedded memory takes more than two third of the chip area in many of today's processors. This trend is expected to increase in future. Memories based on charge storage principle are used since many decades. The greater speed and higher density of memory chips are now achieved at lower costs. However, speed and size are gradually approaching the physical limits. Newer memory concepts are therefore being explored. This paper presents a discussion on different random access memories based on new concepts. An overview of emerging technologies, probable future trends and challenges are described.
