Nonvolatile memory devices with on die termination circuits and control methods thereof

摘要

Non-volatile memory devices including on-die termination circuits connected to an input/output circuit and an on-die termination control logic detecting a preamble of a strobe signal based on a command and a control signal and activating the on-die termination within the preamble period.

主权项

1. A nonvolatile memory device, comprising:
a nonvolatile memory element; an on-die termination circuit in the nonvolatile memory element and connected with an input/output circuit; and an on-die termination control logic configured to detect a preamble period of a strobe signal based upon a command and a control signal and to activate the on-die termination circuit during the preamble period, wherein the on-die termination control logic includes: a first on-die termination controller circuit configured to activate the on-die termination circuit in response to a write operation state signal; and a second on-die termination controller circuit configured to activate the on-die termination circuit in response to a read operation state signal.
