ABSTRACT:
An apparatus and method of tracking accesses in a synchronously accessed memory system so as to enable dynamic sense amplifiers for sensing data at optimal times is described. In one case, the apparatus is used to enable dynamic sense amplifiers in a SRAM in which a memory cell or memory cells within the memory array are accessed by a global word line and one or more sub-word lines. The apparatus includes detection circuitry for detecting when particular GWL and SWL lines are selected and enable circuitry for enabling the appropriate sense amplifier in response to the detection circuitry. Since the enable circuitry for each sense amplifier is responsive to the accessing signals for the particular cell or cells being accessed, the sense amplifier corresponding to the cell or cells being accessed will be enabled at the proper time for reading data from the accessed cell or cells so as to avoid erroneous early reading of data and to avoid delaying reading data to ensure that it is ready.
