Abstract
A system includes a first plurality of memory macros and a first tracking circuit associated with a memory macro of the first plurality of memory macros. Each memory macro of the first plurality of memory macros includes a corresponding global control circuit configured to receive a first reset signal. The first tracking circuit is configured to generate the first reset signal.
Claims20
A system comprising:
- a first plurality of memory macros, each memory macro of the first plurality of memory macros comprising a corresponding global control circuit configured to receive a first reset signal;
- and
- a first tracking circuit associated with a memory macro of the first plurality of memory macros and configured to generate the first reset signal.
A method of forming a memory system, comprising:
- configuring a tracking driver corresponding to a driver of a memory macro of a plurality of memory macros, a ratio of a driving capability of the tracking driver to a driving capability of the driver being a predetermined ratio;
- configuring a tracking load corresponding to a load of the memory macro of the plurality of memory macros, the tracking load being coupled with the tracking driver, a ratio of the tracking load to the load of the memory macro of the plurality of memory macros being the predetermined ratio;
- and
- forming the plurality of memory macros and a tracking circuit shared by the plurality of memory macros in the memory system, the tracking circuit comprising the tracking driver and the tracking load.
