Abstract
A method of operating a storage device including a non-volatile memory includes receiving a write command from a host in a first state, receiving write data from the host in a second state, and transitioning an operation state from the second state to one of the first state and a third state based on a write mode chosen. The write command is received in the first state, and the received write data is programmed to the non-volatile memory in the third state.
Claims22
A method of operating a storage device comprising a non-volatile memory, the method comprising:
- receiving a write command from a host in a first state;
- receiving write data from the host in a second state;
- and
- transitioning an operation state from the second state to one of the first state and a third state based on a write mode chosen,
- wherein the first state is operative to receive the write command, and the third state is operative to program the received write data to the non-volatile memory.
The method of claim wherein the storage device is an embedded multimedia card (eMMC).
-15. (canceled)
A storage device comprising:
- a non-volatile memory;
- and
- a device controller configured to decide on a write mode based on a condition including at least one of an operation mode chosen and a write command and decide whether to enter into a programming state in which data is written to the non-volatile memory, based on the write mode.
A method of operating an embedded multimedia card (eMMC) device comprising a non-volatile memory, the method comprising:
- receiving a write command from a host;
- receiving write data from the host;
- deciding on one of a first write mode in which the storing of the write data in the non-volatile memory is not ensured and a second write mode in which the storing of the write data in the non-volatile memory is ensured to be a write mode;
- wherein when the write mode is the first write mode, transmitting a first state signal indicating a state capable of receiving another write command to the host after the reception of the write data is completed;
- and
- wherein when the write mode is the second write mode, transmitting a second state signal indicating a state incapable of receiving the write command after the reception of the write data is completed,
- wherein the deciding on one of the first write mode and the second write mode is performed after the receiving the write command.
