Abstract
The present disclosure provides a dynamic random access memory (DRAM), and a method of operating the same. The DRAM includes a memory row and a buffer. The memory row is configured to store a data, wherein the memory row does not provide the data to the buffer in response to a request to read the data. The buffer is configured to store the data as a temporarily-stored data, wherein the buffer provides the temporarily-stored data in response to the request.
Claims20
A dynamic random access memory (DRAM), comprising:
- a memory row configured to store a data in response to a first request to access the data, wherein the memory row does not provide the data in response to a second request, following the first request, to read the data;
- and
- a buffer configured to temporarily store the data as a temporarily-stored data in response to the first request, wherein the buffer provides the temporarily-stored data in response to the second request.
A dynamic random access memory (DRAM), comprising:
- a first memory row configured to store a first data;
- a second memory row configured to store a second data;
- a first buffer configured to temporarily store the first data as a first temporarily-stored data in response to a first request to read the first data;
- and
- a second buffer configured to temporarily store the second data as a second temporarily-stored data in response to a second request, following the first request, to read the second data, wherein the first buffer retains the first temporarily-stored data in response to the second request, and
- wherein the first buffer provides the first temporarily-stored data in response to a third request, following the second request, to read the first data.
3 more elements
A method, comprising:
- storing a data and providing the data by a memory row in response to a first request to access the data;
- and
- not providing the data from the memory row in response to a second request, following the first request, to read the data.
