Abstract:
A solid state drive in accordance with embodiments of the present inventive concepts may include a nonvolatile memory, a volatile memory, a memory controller controlling the nonvolatile memory and the volatile memory, and a power generator providing power to the nonvolatile memory, the volatile memory, and the memory controller. A method of operating the solid state drive may include designating a bank that will perform a self refresh among a plurality of banks included in the volatile memory in response to a power saving mode signal. Information of the designated bank may be stored in a register in response to a command and an address signal; and a self refresh of the designated bank may be performed on the basis of the information stored in the register.
Abstract:
An auxiliary power supply device can include a first power storage unit, a first charging circuit to receive input power and charge the first power storage unit, a second power storage unit having lower power supply speed than the first power storage unit and longer power supply time than the first power storage unit, a second charge circuit to receive input power and charge the second power storage unit, and a switching unit to supply the stored power of the first power storage unit to external devices for a predetermined time when a sudden power-off occurs and supply stored power of the second power storage unit to the external devices after the predetermined time elapses.
Abstract:
A user system is provided including a plurality of flash memory devices and a memory controller connected to the flash memory devices through a plurality of channels. The memory controller includes a voltage regulator configured to supply a power of the flash memory devices and a compensation unit configured to supply an additional power to the flash memory devices when a power required by the flash memory devices exceeds a predetermined level. The compensation unit includes a resistor unit connected to an output terminal of the voltage regulator and input terminals of the flash memory devices and a charging unit connected to input terminals of the flash memory devices. The charging unit is configured to supply an additional power to the flash memory devices according to voltages of input terminals of the flash memory devices.
