Abstract:
1. A method for accessing a dynamic random access memory (DRAM), the DRAM having a plurality of memory storage elements arranged in rows and columns, the method comprising steps of: a) initiating a first memory access by providing a first address signal indicative of the location of at least one memory storage element to be accessed; b) decoding the first address signal to select a row and at least one column corresponding to the location of the at least one memory storage element; c) enabling a word line corresponding to the selected row; d) activating a sense amplifier to latch data to or from the at least one selected column; e) disabling the word line corresponding to the selected row; f) precharging the at least one selected column; g) initiating a second memory access by providing a second address signal indicative of the location of at least one memory storage element to be accessed; and h) decoding the second address signal to select a row and at least one column corresponding to the location of the at least one memory storage element, the second memory access commencing before the step of precharging the selected column has completed.
