Address dependent wordline timing in asynchronous static random access memory
A static random access memory (SRAM) has one or more arrays of memory cells, each array of memory cells activated in columns by a wordline. The activated column of memory cells asserts output data onto a plurality of bitlines coupled to output drivers. The SRAM includes a wordline controller generating a variable pulse width wordline which may be reduced sufficient to introduce memory read errors. Each of a high error rate, medium error rate, low error rate, and error-free rate is associated with a pulse width value generated by the wordline controller. A power consumption tradeoff exists between the wordline pulse width and consumed SRAM power. The wordline controller is thereby able to associate a wordline pulse width to an associated error rate for performing tasks which are insensitive to a high error rate or a medium error rate, which are specific to certain neural network training and inference using various NN data types.
