Abstract

Provided is a calibration circuit and operating method of the calibration circuit. The calibration circuit includes a first resistor code output circuit and a second resistor code output circuit. The first resistor code output circuit is coupled to an external resistor through an input / output pad, performs a first calibration operation, based on a first resistor value, such that a target voltage applied to a first reference node coupled to the input / output pad has a set voltage level, and outputs a first resistor code as a result obtained by performing the first calibration operation. The second resistor code output circuit receives the target voltage, sets an internal resistor value, based on the first resistor code, performs a second calibration operation, based on a second resistor value different from the first resistor value, and outputs a second resistor code as a result obtained by performing the second calibration operation. The first resistor value is a resistor value of the first resistor.

Description

technical field [0001] The present disclosure generally relates to an electronic device, and more particularly, to a calibration circuit and a method of operating the calibration circuit Background technique [0002] A storage device is a device that stores data under the control of a host device such as a computer or a smartphone. The storage device may include a memory device for storing data and a memory controller for controlling the memory device. Memory devices are classified into volatile memory devices and nonvolatile memory devices. [0003] Volatile memory devices are memory devices that store data only while power is supplied, and the stored data is lost when power is interrupted. Volatile memory devices may include static random access memory (SRAM) and dynamic random access memory (DRAM), among others. [0004] A nonvolatile memory device is a memory device in which data is not lost even when power is interrupted. Nonvolatile memory devices may include read ...
