Abstract
An efficient invention for opening two pages of memory for a DRAM are discussed.
Claims21
A method comprising:
- opening a first page of memory in a first memory bank with a single command to the memory;
- opening a second page of memory in a second memory bank with the single command to the memory in parallel to the first page based at least in part on the second memory bank being adjacent to the first memory bank.
A method comprising:
- opening two pages of memory in a first memory bank pair with a first command to the memory for a first cache line fill memory operation;
- opening two pages of memory in a second memory bank pair with a second command to the memory for a second cache line fill memory operation;
- and
- completing the second cache line fill memory operations after the first cache line fill memory operation.
1 more element
An apparatus comprising:
- a processor, coupled to a cache memory, the cache memory to open two pages of memory in a first memory bank pair with a first command for a first cache line fill memory operation and to open two pages of memory in a second memory bank pair with a second command for a second cache line fill memory operation;
- and
- the apparatus to complete the second cache line fill memory operations after
- the first cache line fill memory operation.
1 more element
A memory comprising:
- a logic to support a first page of memory in a first memory bank to be opened with a single command to the memory and a second page of memory in a second memory bank to be opened with the single command to the memory in parallel to the first page based at least in part on the second memory bank being adjacent to the first memory bank.
A memory comprising:
- a logic to support two pages of memory in a first memory bank pair to be opened with a first command to the memory for a first cache line fill memory operation and another two pages of memory in a second memory bank pair to be opened with a second command to the memory for a second cache line fill memory operation;
- and
- the second cache line fill memory operation to be completed after the first cache line fill memory operation.
