    摘要: A memory system includes a memory device having a plurality of non-volatile memories, a buffer chip connected with each of the plurality of non-volatile memories, and a memory controller connected with the buffer chip and configured to provide a data strobe signal and a data signal to the buffer chip. The buffer chip includes a first loop coupled to a sampler circuit and configured to perform first monitoring on the data strobe signal and first duty correction on the data strobe signal based on the first monitoring, and a second loop coupled to a multiplexer and configured to, responsive to the first duty correction, perform second monitoring on the data strobe signal and second duty correction on the data strobe signal based on the second monitoring. The buffer chip is configured to store first and second duty correction information for at least one of the plurality of non-volatile memories.

    摘要: A storage device includes NVM package and a controller connected to the NVM package through a channel and controlling operation of the NVM package. The NVM package includes an interface chip, first NVM devices connected to the interface chip through a first internal channel and second NVM devices connected to the interface chip through a second internal channel. The interface chip selects the first internal channel in response to an operation request received from the controller and connects the first internal channel to the channel. The interface chip also determines whether retraining is necessary in relation to the second internal channel and transmits a retraining request to the controller when retraining is necessary.
