A multiprocessor system includes first and second processors and a multi-path accessible semiconductor memory device including a shared memory area and a pseudo operation execution unit. The shared memory area is accessible by the first and second processors according to a page open policy. The pseudo operation execution unit responds to a virtual active command from one of the first and second processors to close a last-opened page. The virtual active command is generated with a row address not corresponding to any row of the shared memory area. For example, bit-lines of a last accessed row are pre-charged for closing the last-opened page.

Disclosed is an apparatus and a method for improving the receive (Rx) sensitivity of a portable Radio Frequency IDentification (RFID). The portable RFID reader/writer is equipped with a variable phase shifter which is connected between an antenna and a directional coupler and then changes an impedance in the direction of the antenna in response to controlling a phase shift, a level of a reflection signal if a transmit (Tx) signal of the portable RFID reader/writer reflected by the antenna flows into an Rx path is measured, and then the phase shift of the variable phase shifter is controlled in such a manner as to minimize the measured level of the reflection signal. Therefore, calibration is implemented so that an antenna impedance changing in response to a position in which contact is made by a user's hand may have an adaptively optimal antenna reflection coefficient, thereby improving the Rx sensitivity.

A button for providing visual-haptic information includes a visual-haptic variable button that adaptively provides various types of visual-haptic information according to input of information to an electronic apparatus. The visual-haptic variable button includes a visual information output part that adaptively changes various types of button icons according to manipulation and touch of the visual-haptic variable button for the input of information, thereby outputting visual information, and a haptic information output part that adaptively changes various types of sense of button manipulation and sense of button touch according to the manipulation and touch of the visual-haptic variable button, thereby outputting haptic information. At least one visual-haptic variable button is provided in the electronic apparatus for the input of information.
