Abstract
Provided are a storage device and a user device used by connecting to the user device. The storage device may include a nonvolatile memory and a control unit configured to control the nonvolatile memory. When write data is received from the host, the control unit outputs a first response signal including information indicating whether the write data is successfully received. When the write data is stored in the nonvolatile memory, the control unit outputs a second response signal including on whether the write data is successfully stored in the nonvolatile memory. Since the storage device does not require a program backup memory, it may be implemented in a small area.
Claims20
A storage device, comprising:
- a nonvolatile memory;
- and
- a control unit configured to control the nonvolatile memory,
- wherein the control unit outputs a first response signal comprising information indicating whether a first write data is successfully received from a host, and
- wherein the control unit outputs a second response signal comprising information indicating whether the first write data is successfully stored in the nonvolatile memory.
A user device, comprising:
- a processing unit which outputs a first write data to a storage device;
- and
- a host memory which temporarily stores the first write data,
- wherein the processing unit determines whether to re-transmit the first write data in response to a first response signal from the storage device, and
- wherein the processing unit determines whether to re-transmit the first write data in response to a second response signal from the storage device,
- wherein the processing unit determines whether to erase the first write data stored in the host memory in response to the second response signal from the storage device.
A storage device, comprising:
- a nonvolatile memory;
- and
- a control unit configured to output a first response signal in response to first write data received from a host and output a second response signal in response to the first write data being stored in the nonvolatile memory.
