MEMORY ARRAY PULSE WIDTH CONTROL

摘要

A clock system includes a local clock buffer adapted to receive a variable global clock signal. The local clock buffer produces a first local clock signal from the variable global clock signal. The clock system includes a pulse width logic control circuit in operable communication with the local clock buffer. The pulse width logic control circuit may be adapted to limit the first local clock signal pulse width to be less than the variable global clock signal pulse width during a slow mode. The pulse width logic control circuit may be adapted to expand the first local clock signal pulse width to be greater than the variable global clock signal pulse width during a fast mode. The limited and expanded first local clock signals may signal a local evaluation circuit to address a memory line.
