Abstract
A data writing method and a memory, in which the data writing method is used for writing data to a memory array of the memory. The data writing method includes that: old data is read from a target column of the memory array; the old data is updated according to data to be written which carries target data bits information to generate new data; and the new data is written into the target column, in which the memory includes a plurality of data columns, the data is required to be written into the target column, and the target column includes a part of the data columns.
Claims13
A data writing method, used for writing data into a memory array of a memory, comprising:
- reading old data from a target column of the memory array;
- updating the old data according to data to be written which carries target data bit information to generate new data;
- and
- writing the new data into the target column,
- wherein the memory comprises a plurality of data columns, the data to be written is required to be written into the target column, and the target column includes a part of the plurality of data columns,
- wherein updating the old data according to the data to be written which carries the target data bit information to generate the new data comprises:
- covering data of target data bits in the old data according to the data to be written, to generate the new data.
A memory, comprising:
- a memory array, comprising a plurality of data columns;
- and
- a controller, connected with the memory array and configured to control the memory array to perform a data writing method, wherein the data writing method comprises:
- reading old data from a target column of the memory array;
- updating the old data according to data to be written which carries target data bit information to generate new data;
- and
- writing the new data into the target column,
- wherein the data to be written is required to be written into the target column, and the target column includes a part of the plurality of data columns,
- wherein updating the old data according to the data to be written which carries the target data bit information to generate the new data comprises:
- covering data of target data bits in the old data according to the data to be written, to generate the new data.
