Abstract: A write data input circuit for a double data rate (DDR) SDRAM acquires write data at both a rising and falling edge of a clock signal. The input circuit includes a command input buffer for receiving external commands, such as a read, write or refresh command. An external command latch circuit connected to the input buffer latches the external command in sync with a first clock signal. A decoder decodes the latched external command. A write determination circuit also receives the (undecoded) external command and generates an enable signal if the external command is a write command. A data input buffer is activated by the enable signal and receives write data. A data latch circuit latches the write data provided to the data input buffer in sync with a second clock signal.

Abstract: When a pin layer magnetic field offset judgment unit judges that a magnetic field in a pin layer of a spin valve head through which a sense current flows in the interference direction has been deviated from a normal direction, a recovery processing unit allows a recovery from the abnormality arising from the magnetic field offset. For example, the direction of the sense current is switched from the interference direction to the assist direction, and the sense current larger than that upon the ordinary reading action is allowed to flow so that the temperature of an antiferromagnetic layer exceeds the blocking temperature, whereby the direction of the magnetic field in the pin layer is modified to the normal direction by the action of a magnetic field generated from the sense current. After the modification, the sense current is returned to have its ordinary value in the interference direction.
