Abstract
An integrated circuit includes an array of memory cells that are selected by rows and read by columns. The columns are first precharged by an internal signal to then read the memory cells. The read is responsive to an edge of a clock signal and the read is of an unknown delay. A multiplexer output provides the internal signal. The multiplexer includes a plurality of inputs electrically connected to delay lines of different delay sizes that receive the edge of the clock signal. A multiplexer control circuit selects a delay line to provide the internal signal as soon as possible after the unknown delay.
