Abstract
To ensure proper functioning of a memory component, the memory cells may be initialized to a known value before the memory device is used. The known values are termed the “background pattern.” The memory cells may also be reset to the background pattern to scrub data memory for security. Typically, standard write operations are used to write the background pattern. As discussed herein, multiple addresses on a single word line can be written to simultaneously. As also discussed herein, when the same data is written to multiple word lines, the step of copying the data to the sense amplifiers may be performed once instead of repeated for each write command, further reducing the time consumed by writing background patterns to a memory array.
Claims20
A memory system comprising:
- a memory component comprising a number of bit lines, a plurality of word lines, and a number of sense amplifiers equal to the number of bit lines;
- and
- a processing device programmed to perform operations comprising:
- setting data values in the number of sense amplifiers;
- and
- using the sense amplifiers, writing the data values to memory cells corresponding to the plurality of word lines.
A method comprising:
- setting data values in a number of sense amplifiers of a memory component, the number of sense amplifiers equal to a number of bit lines of a word line of the memory component;
- and
- using the sense amplifiers, writing the data values to memory cells corresponding to a plurality of word lines of the memory component.
A non-transitory machine-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- setting data values in a number of sense amplifiers of a memory component, the number of sense amplifiers equal to a number of bit lines of a word line of the memory component;
- and
- using the sense amplifiers, writing the data values to memory cells corresponding to a plurality of word lines of the memory component.
