Abstract
A semiconductor memory device comprises first and second memory sections including a plurality of memory elements, and a memory control section for allowing a data transfer operation between the first and second memory sections based on an external control command while allowing a memory operation to at least one of the first and second memory sections. At least one of the first and second memory sections include a plurality of small memory regions, and the memory control section allows each of the plurality of small memory regions to be separately and simultaneously subjected to an access operation.
Claims21
A semiconductor memory device, comprising:
- first and second memory sections including a plurality of memory elements;
- and
- a memory control section for carrying out a data transfer operation between the first and second memory sections based on an external control command while carrying out a memory operation to at least one of the first and second memory sections,
- wherein at least one of the first and second memory sections include a plurality of small memory regions, and
- the memory control section allows each of the plurality of small memory regions to be separately and simultaneously subjected to an access operation.
A semiconductor memory device, comprising:
- first and second memory sections including a plurality of memory elements;
- and
- a memory control section for carrying out a data transfer operation between the first and second memory sections based on an external control command while carrying out a memory operation to at learnt one of the first and second memory sections,
- wherein the memory control section has an access operation section for limiting an access period for at least one of the first and second memory sections to a minimum of that required for each access operation.
