Abstract
The invention discloses a memory management system and a memory management method are disclosed. The memory management system includes a first memory, at least one secondary memory, and a memory management device. The first memory includes a normal access memory bank and at least one switching access memory bank. The secondary memory includes at least one secondary access memory bank corresponding to the switching access memory bank. The memory management device reads/writes the normal access memory bank or the secondary access memory bank.
Claims12
A memory management system, comprising:
- a first memory including a normal access memory bank and at least one switching access memory bank;
- at least one secondary memory including at least one secondary data bank corresponding to the switching access memory bank;
- and
- a memory management device for reading/writing the normal access memory bank or the secondary data bank according to at least one request signal, and the memory management device comprising a memory switching controller and a direct memory access controller;
- wherein the memory switching controller stores the data into the switching access memory bank and writes the data stored in the switching access memory bank into the secondary data bank via the direct memory access controller when the request signal is designated to write the data to be written into the secondary data bank.
A memory management system, comprising:
- a memory switching controller for generating a control signal according to at least one request signal;
- a first memory including a normal access memory bank and at least one switching access memory bank, wherein the plurality of access memory banks are switched according to the control signal, and the normal access memory bank or the switching access memory bank is read out or written in according to the control signal;
- at least one secondary memory including at least one secondary data bank corresponding to the switching access memory bank;
- and
- a direct memory access controller for moving the data in the secondary data bank to the switching access memory bank or writing data that are to be written into the secondary data bank via mapping the switching access memory bank according to the control signal, wherein the memory switching controller moves the data stored in the secondary data bank to the switching access memory bank and outputs the data stored in the switching access memory bank via the direct memory access controller when the request signal is designated to access the data of the secondary data bank.
