Abstract
An apparatus comprising a memory array including a plurality of memory cells arranged in a plurality of columns and a plurality of rows is provided. The apparatus further comprises circuitry configured to perform an error detection operation on the memory array to determine a raw count of detected errors, to compare the raw count of detected errors to a threshold value to determine an over-threshold amount, to scale the over-threshold amount according to a scaling algorithm to determine a scaled error count, and to store the scaled error count in a user-accessible storage location.
Claims17
An apparatus, comprising:
- a memory array including a plurality of memory cells arranged in a plurality of columns and a plurality of rows;
- and
- circuitry configured to:
- perform an error detection operation on the memory array to determine a raw count of detected errors,
- scale the raw count with either a with either a logarithmic scale or a linear scale to determine a logarithmically or linearly scaled error count, and
- store the logarithmically or linearly scaled error count in a user-accessible storage location.
A method comprising:
- performing an error detection operation on a memory array to determine a raw count of detected errors;
- scaling the raw count with either a with either a logarithmic scale or a linear scale to determine a logarithmically or linearly scaled error count;
- and
- storing the logarithmically or linearly scaled error count in a user-accessible storage location.
An apparatus, comprising:
- a memory array comprising a plurality of memory cells arranged in a plurality of columns and a plurality of rows;
- and
- circuitry configured to:
- perform an error detection operation on the memory array to determine a raw count of detected errors and an initial highest detected error count,
- scale the raw count of detected errors with either a with either a first logarithmic scale or a first linear scale to determine a logarithmically or linearly scaled total error count,
- scale the initial highest detected error count with either a with either a second logarithmic scale or a second linear scale to determine a logarithmically or linearly scaled highest error count, and
- store the logarithmically or linearly scaled total error count and the logarithmically or linearly scaled highest error count in a user-accessible storage location.
