摘要： An array of memory cells is physically divided into a data area and a tag area so that respective parts of the two areas share a word line but can be separately erased en bloc. The data area and tag area sharing one word line constitute a single logical unit. In the logical unit, the tag area stores location information for defective memory cells in the corresponding data area. On the basis of this information, the system avoids the use of the defective memory cells. The defective memory cell information is programmed in a test step performed after chip manufacture and, at the same time, ECCs are generated for the defective memory cell information and written to the tag area. Furthermore, the system is informed of the invalidity of the data area that shares a word line with a tag area by writing predetermined data to the tag area. Even when the data area is erased en bloc, the tag area is not erased and the defective memory cell information is retained there.

摘要： In case of rewriting data by means of an erasable optical disc memory recording new data after having erased a series of data already stored, directory data written in an optical disc memory in order to control the written data are transferred to an external directory memory and write-in and read-out are controlled by using the directory memory. For rewriting data, which have been already recorded and which are recorded under a specified file name, the data are not erased and renewed data are written in another recording region, where recording is possible. The data, which have become unnecessary as the result of renewal, are erased during a period of time, when the optical disc memory is not accessed.

摘要： A series resonant drive circuit for a magnetic bubble memory includes X- and Y-coils arranged orthogonally to each other for generating a rotating magnetic field applied to a magnetic bubble memory chip, resonance capacitors each connected to a corresponding one of the X- and Y-coils for forming a series resonance circuit with the corresponding coil at a frequency of the rotating magnetic field, power supplies each connected to a corresponding one of the resonance circuits, and an inductance device connected in series with both of the resonance circuits and a capacitance device connected between the resonance circuits to compensate a mutual inductance due to the inductive coupling between the X- and Y-coils and a capacitance due to the capacitive coupling between the X- and Y-coils. Further, the temperature coefficient of the capacitance device is selected so that the temperature coefficients of the mutual inductance and capacitance between the coils can be compensated.

摘要： A projector includes a light source unit that supplies light, and a spatial light modulator that modulates light supplied from the light source unit according to an image signal. The spatial light modulator is driven by an applied voltage whose polarity is reversed according to a polarity-reversing frequency which is specific to the spatial light modulator. The light source unit supplies light which is modulated according to pulse width modulation for which fundamental frequency is set based on the polarity-reversing frequency.
