Title:
MEMORY FAILURE DETECTION AND RESOURCE ALLOCATION
Document Type and Number:
WIPO Patent Application WO/2019/236168
Kind Code:
A3
Abstract:
The present disclosure is directed to a device, a method, and a non-transitory computer readable medium for determining a level of uncertainty of programmed states of memory cells. In one aspect, a memory device includes memory cells, an uncertainty prediction circuit coupled to the memory cells, and a data conversion circuit coupled to the memory cells. The uncertainty prediction circuit is configured to determine, from a subset of the memory cells coupled to a word line, a number of memory cells having a predetermined state. The data conversion circuit is configured to apply a data conversion to a portion of data stored by the subset of the memory cells, in response to the uncertainty prediction circuit determining that the number of memory cells is between a first threshold and a second threshold.
