Abstract
A memory and a method of storing data in a memory are provided. The memory comprises a memory block comprising data bits and additional bits. The memory includes logic which, when receiving a first command, writes data into the data bits of the memory block, wherein the data is masked according to a first input. The logic, in response to a second command, writes data into the data bits of the memory block and writes a second input into the additional bits of the memory block.
Claims10
A system, comprising:
- a processor;
- and
- a memory;
- wherein the memory is communicatively connected to the processor by a memory bus channel;
- wherein the memory comprises:
- a memory block comprising data bits and additional bits;
- and
- logic configured to:
- receive a first and a second input;
- mask data in response to the first input;
- respond to a first command, wherein the response includes:
- writing the masked data into the data bits of the memory block, and writing “don't care” values into the additional bits of the memory block;
- and
- respond to a second command, wherein the response includes:
- writing the data into the data bits of the memory block, and
- writing the second input into the additional bits of the memory block.
