Abstract
A main memory system includes a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory, the main memory system being configured such that, when entering a sleep mode, the memory device reads a portion of data stored in the first memory device to store the read data in the second memory device, and, after the portion of data is read, the first memory device and the second memory device are powered off.
Claims30
A main memory system comprising:
- a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory,
- the main memory system being configured such that, when entering a sleep mode, the memory device reads a portion of data stored in the first memory device to store the read data in the second memory device, and, after the portion of data is read, the first memory device and the second memory device are powered off
A computer system comprising:
- a call processor configured to run a realtime operating system;
- an application processor configured to run a general purpose operating system;
- and
- a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory, the main memory device configured to store data for operations of the call processor and the application processor, and configured to, when entering a high-level sleep mode, read a portion of data stored in the first memory device to store the read data in the second memory device, and then the first memory device and the second memory device are powered off.
A computer system comprising:
- a call processor configured to drive a realtime operating system;
- an application processor configured to drive a general purpose operating system;
- a push notification controller configured to count a reference time interval during a sleep mode to activate the call processor periodically in accordance with the reference time interval;
- and
- a main memory device configured to store data for operations of the call processor and the application processor,
- the computer system being configured such that the main memory device is powered off during the sleep mode and only a portion of the main memory device is activated when the computer system receives a transmission signal from an external device during the sleep mode.
A method of operating a system including a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory, the method comprising:
- reading a portion of data stored in the first memory device in response to a sleep mode signal;
- storing the read data in the second memory device;
- entering a sleep mode by powering off the first memory device and the second memory device after the read data are stored in the second memory device;
- receiving a transmission signal from an external device;
- and
- maintaining the sleep mode after receiving the transmission signal.
A computing system comprising:
- a main memory device including a first memory device implemented with a volatile memory and a second memory device implemented with a non-volatile memory;
- and
- a power management unit configured to control a supply of power to the main memory device,
- the computing system being configured such that, when the main memory device enters a sleep mode,
- the main memory device reads data stored in the first memory device,
- the main memory stores the read data in the second memory device, and
- after the read data is stored in the second memory device, the power management unit powers off the first memory device and the second memory device.
