    摘要: An apparatus for floating read bitlines of a static random access memory (SRAM) is disclosed. The SRAM includes a first and second SRAM cell columns, a first and second read bitlines, and a multiplexor. The multiplexor is coupled to the first and second SRAM cell columns via the first and second read bitlines, respectively. The multiplexor is capable of selectively transmitting data from the first or second SRAM cell column via the first or second read bitline, respectively, to an output. In addition, the multiplexor allows the first read bitline and/or the second read bitline to remain uncharged when no data are being read from the first SRAM cell column and/or the second SRAM cell column.

    摘要: A method, computer program product and system for testing stuck-at-faults. A first register may be loaded with a first value where the first value may be written into each entry in a memory array. A second register may be loaded with a second value. A third register may be loaded with either the second value or a third value. The second and third values are pre-selected to test selector circuits for stuck-at-faults with a pattern where the pattern includes a set of bits to be inputted to selector circuits and a set of bits to be stored in the memory cells. A value stored in the n-most significant bits in both the second and third registers may be predecoded to produce a predecode value. The predecode value may be compared with the value stored in the n-most significant bits in an entry in the memory array to determine a stuck-at-fault.
