Abstract
Embodiments described herein aim to optimize the Erratic Program Detection (EPD) process by eliminating unnecessary operations and adjusting operations that are not optimized for the EPD process. For example, one optimization includes the EPD read operations being performed based on a read mode optimized for faster data retrieval. Further, another optimization includes a first read voltage ramping up at a rate that is faster than a ramp rate used to ramp up a read voltage during performance of a normal read operation. Another optimization also includes a read voltage kick operation between the EPD read operations being eliminated. Finally, another optimization includes parallelizing the scan operation with other ongoing operations.
