Abstract
A non-volatile memory device, a storage device including the non-volatile memory device, and an operating method of the storage device are provided. The non-volatile memory device comprises a data pin configured to output a data signal, and a command address pin being separate from the data pi the command address pin configured to receive a read command corresponding to the data signal and output a noise state data during a data output operation in which the data signal is output through the data pin in response to the read command.
Claims20
A non-volatile memory device comprising:
- a data pin configured to output a data signal;
- and
- a command address pin being separate from the data pin, the command address pin configured to,
- (i) receive a read command corresponding to the data signal, and
- (ii) output a noise state data through the command address pin during a data output operation in which the data signal is output through the data pin in response to the read command.
A storage device comprising:
- a first non-volatile memory device and a second non-volatile memory device connected to a first channel, the first non-volatile memory device and the second non-volatile memory device configured to perform a data input/output operation through the first channel;
- and
- a storage controller configured to
- provide a data input/output command for the data input/output operation to the first non-volatile memory device through a command address pin connected to the first channel,
- perform the data input/output operation for the first non-volatile memory device through a data pin connected to the first channel, the data pin being different from the command address pin, and
- receive a noise state data on at least one of the first and the second non-volatile memory devices in parallel with the data input/output operation through the command address pin.
An operation method of a storage device comprising:
- providing a data input/output command through a command address pin;
- performing a data input/output operation through a data pin different from the command address pin based on the data input/output command;
- providing a noise monitoring command through the command address pin according to a condition during the data input/output operation;
- and
- receiving a noise state data through the command address pin in response to the noise monitoring command during the data input/output operation.
