Abstract
Described herein are embodiments of methods and systems of using a timer based memory buffer for metrology. One embodiment of the method comprises receiving metrology data from one or more metrology sensors; writing at least part of the metrology data to a volatile memory; incrementing a write pointer to indicate the metrology data contained within the volatile memory; and repeating the above until a timer expires, then reading at least a portion of the metrology data from the volatile memory.
