Advanced Memory Technology and Architecture

Synopsis

A video recording of a short course held by the International Electron Devices Meeting (IDEM) in 2001. The explosive evolution of digital information technologies require innovation not only in logic devices but also in the semiconductor memory systems. For example, next generation cellular phones will need much larger memory capacity for digital signal processing than present systems, the use of DRAM cache can reduce MPU power, and, in the distant future, main memory may be substituted by high density non-volatile memory. Under these IT market needs, continuing efforts in process and circuit technologies have led to realization of commercially available Giga-bits DRAM within a few years. Performance improvement towards higher bandwidth also continues in SDRAM or RDRAM, adopting the novel system architectures to cope with aggressively increasing MPU operation frequency. Embedded DRAM with high bandwidth and low latency has already been introduced for graphic applications. In SRAM, high speed cache with the operating speed over 1 GHz has been developed with deep sub-micron technology. Power management is also an important issue, especially for the SRAM used in mobile applications. Recently, the non-volatile memory market has been growing much more rapidly than other fields, thanks to the growth of portable multimedia devices. The NAND flash memory for mass data storage, the NOR flash memory for stand-alone and embedded applications, and the EEPROM for the smart card have been leading the market. These devices, however, have programming speed and endurance limitation. To overcome these drawbacks, development of the emerging technologies such as FeRAM or non-volatile magnetoresistive RAM (MRAM) is in progress. This course starts with an overview of the MPU architecture evolution and its influence on memory architecture. The second lecture presents the leading edge process and device technologies for Giga-bits DRAM. The third lecture describes state-of-the-art SRAM device and circuit technologies. The fourth lecture deals with non-volatile memory, and the appropriate device solution for each application is discussed. The final lecture shows potential of MRAM device as a promising candidate of the future non-volatile memory.
