Abstract: A password input system equipped with a security setting function is disclosed. The system includes one input unit configured to receive an input from user; an output unit configured to output a current state and result; a dedicated communication port configured to transmit and receive data to and from a password adaptor; a memory configured to save a program for security setting function; and a processor configured to execute the program saved in memory. When the processor waits for an input of a password from user and simultaneously password adaptor is coupled to dedicated communication port, the processor receives a password through communication with password adaptor and compares received password with a pre-saved password, and when the received password matches the pre-saved password, the processor unlocks a secure state without further inputting a password.

Abstract: A multi-mode hybrid memory drive comprises a bulk memory device and a removable cache memory device. A controller of the bulk memory device may be configured to operate the bulk memory device in either a stand-alone mode or a hybrid mode responsive to detecting the removable cache memory device being coupled with a cache port of the bulk memory device. A method of operating a multi-mode hybrid drive may also comprise monitoring a cache port of a bulk memory device to determine a presence of a removable cache memory device, operating the bulk memory device as a stand-alone drive responsive to determining the removable cache memory device is not present, and operating the bulk memory device as a hybrid drive using the removable cache memory device as a data cache responsive to determining the removable cache memory device is present. Additional hybrid memory drives and computer systems are also described.
