Abstract: A storage system includes a plurality of DRAM-less storage devices, a CXL memory expander, and a PLP capacitor. The DRAM-less storage devices include nonvolatile memories as a storage medium, and a DRAM is omitted in the DRAM-less storage devices. The CXL memory expander is electrically connected to the DRAM-less storage devices, communicates through a CXL interface and operates as a buffer memory of the DRAM-less storage devices. The PLP capacitor is electrically connected to the DRAM-less storage devices and the CXL memory expander, is disposed outside the DRAM-less storage devices, and supplies an auxiliary power voltage to the DRAM-less storage devices and the CXL memory expander in a SPO condition in which an external power voltage is suddenly turned off.

Abstract: A electronic device includes a controller and a power supply. The controller stores a table including gate signal frequencies and numbers of power transistors for plural operations, and based on the table and an operation request to perform an operation, outputs a power control signal including one or both of gate signal frequency for the operation and a number of power transistors for the operation. The power supply includes plural power transistors that receive gate signals. The power supply, based on the power control signal, generates one or more gate signals input to one or more power transistor among the plural power transistors, and, based on turn-on of the one or more power transistors, generates a load supply voltage based on a system supply voltage.

Abstract: A storage device may include a storage medium, a storage device controller coupled to the storage medium, a host interface coupled to the storage device controller, and an attachable module interface configured to connect an attachable compute module to the storage device controller. The attachable module interface may include a data interface, a side-band interface, and/or a power interface. The attachable module interface may include a connector configured to connect the attachable compute module to the storage device controller. The storage device may include an enclosure having an opening configured to enable the attachable compute module to be connected to the attachable module interface through the opening. The storage device controller may be configured to utilize one or more resources of the attachable compute module. The storage device controller may be configured to communicate with the attachable compute module through one or more command extensions of a storage protocol.
