Abstract
A memory has a tracking circuit for a read tracking operation. The memory includes a memory bit cell array, a tracking column, a tracking row, a sense amplifier row coupled to the memory bit cell array and the tracking row, and a sense amplifier enable logic. The memory further includes a tracking bit line coupled to the tracking column and the sense amplifier enable logic, and a tracking word line coupled to the tracking row and the sense amplifier enable logic. The tracking circuit is configured to track a column time delay along the tracking column before a row time delay along the tracking row.
