2012, Master of Science, University of Akron, Electrical Engineering.
This work discusses the design of a static random access memory (SRAM) capable of operating over a temperature range of 27oC to 120oC. A standard six-transistor SRAM cell is used to implement a 1Kword SRAM where each word is sixteen bits. The conventional array architecture is used. The control circuit is implemented using asynchronous approach. Careful consideration is given to the stability of the SRAM cell and the performance of the memory. The stability margins considered include the read static noise margin, the hold static noise margin and the write static noise margin. These stability margins are discussed in detail and the effect of temperature on stability is discussed. Four designs are included: the Baseline Design, the Modified Design I, the Modified Design II and the Modified Design III. The device geometries of the SRAM cell are adjusted to have acceptable read and write static noise margins at 27oC and 120oC. The most stable of the designs shows a 10% increase in read stability margin with a 2.6% increase in read access time relative to the baseline design. It is observed that the stability was improved at the cost of slightly reduced speed. The designed SRAM has an acceptable stability over temperature.
