Abstract:
A strobe signal shaping method for a data storage system includes receiving a strobe signal; boosting a first clock edge portion of the strobe signal when the strobe signal is received after having been idle or paused over a predetermined time period; and returning to an operating mode in which boosting is turned off with respect to a second clock edge portion of the strobe signal.
Abstract:
A nonvolatile memory device includes a first pin that receives a first signal, a second pin that receives a second signal, third pins that receive third signals, a fourth pin that receives a write enable signal, a memory cell array, and a memory interface circuit that obtains a command, an address, and data from the third signals in a first mode and obtains the command and the address from the first signal and the second signal and the data from the third signals in a second mode. In the first mode, the memory interface circuit obtains the command from the third signals and obtains the address from the third signals. In the second mode, the memory interface circuit obtains the command from the first signal and the second signal and obtains the address from the first signal and the second signal.

Abstract:
A semiconductor memory device includes a peripheral circuit structure, and a cell array structure provided thereon and including a plurality of cell array regions and an upper peripheral region provided between a plurality of cell array regions. A cell array structure includes vertical cell transistors, first vertical peripheral transistors, and second vertical peripheral transistors. Each of vertical cell transistors, a first vertical peripheral transistors, and a second vertical peripheral transistors has a channel extending along a third direction parallel to an arrangement direction of a peripheral circuit structure and a cell array structure. Vertical cell transistors are disposed in a cell array region and have a first polarity. First vertical peripheral transistors are disposed in an upper peripheral region and have a first polarity. Second vertical peripheral transistors are disposed in an upper peripheral region and have a second polarity different from a first polarity.
Abstract:
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.
