Abstract
Examples of the present disclosure provide apparatuses and methods for error code calculation. The apparatus can include an array of memory cells that are coupled to sense lines. The apparatus can include a controller configured to control a sensing circuitry, that is coupled to the sense lines, to perform a number of operations without transferring data via an input/output (I/O) lines. The sensing circuitry can be controlled to calculate an error code for data stored in the array of memory cells and compare the error code with an initial error code for the data to determine whether the data has been modified.
Claims20
An apparatus comprising:
- an array of memory cells that are coupled to a plurality of sense lines;
- a plurality of sense amplifiers coupled to the plurality of sense lines;
- and
- a controller configured to:
- control a compute component, that is coupled to at least one of the plurality of sense amplifiers, to perform a number of operations to:
- calculate an error code for data stored in the array of memory cells;
- and
- compare the error code with an initial error code for the data to determine whether the data has been modified.
A method, comprising:
- controlling a compute component that is coupled to a sense amplifier, which is coupled to an array of memory cells, to perform a number of operations including:
- calculating an error code for data stored in the array of memory cells;
- and
- comparing the error code with an initial error code for the data to determine whether the data has been modified.
A system comprising:
- a host;
- a memory device coupled to the host, the memory device including:
- an array of memory cells that are coupled to a plurality of sense lines;
- a plurality of sense amplifiers coupled to the plurality of sense lines;
- and
- a controller configured to control a plurality of compute components coupled to the plurality of sense amplifiers, to perform a number of operations to:
- calculate an error code for data stored in the array of memory cells;
- and
- compare the error code with an initial error code for the data to determine whether the data has been modified.
