Abstract
A timing circuit produces a clock signal. An address buffer circuit receives and stores a first address in a first latch and a second address in a second latch asynchronously with respect to the clock signal. A memory control circuit associated with an array of memory cells accesses a first memory cell in the array corresponding to the first address in a first clocked access cycle, and accesses a second memory cell in the array corresponding to the second address in a second clocked access cycle. If a further address is asynchronously received before said second access cycle, the further address replaces the second address in the second latch.
