A unit detachably mountable to an apparatus main assembly is provided with a coupling for receiving a rotational driving force from the apparatus main assembly. Also the apparatus main assembly is provided with a coupling to be engaged with the coupling of the unit. At least one of these couplings can be pushed in a direction parallel to a rotation shaft and one of the couplings is provided with an inclined surface. During mounting and demounting of the unit, the engagement between the couplings is released by the pushing in of one of the couplings pushed by the inclined surface.

In a case that a bare chip has been detected as being defective from among bare chips, a good chip is mounted to the rear surface of the surface wherein the bare chips are provided to a semiconductor module substrate so that a QFC pin of the bare chip is fixed at the ground potential (GND). Thereby, the bare chip stops the output of a signal to the input/output terminals or the input of a signal from the input/output terminals. As a result, the good chip outputs an electrical signal to the input/output terminals or an electrical signal is inputted from the input/output terminals. Thereby, a semiconductor module is gained that can be repaired even in the case that a defective chip is detected after the chip has been molded into a mold resin.

In a serial memory, data signal holding circuits for temporarily holding data read from memory cells are provided as a data register. One holding circuit includes a latch circuit and capacitors connected to input/output nodes of the latch circuit, respectively. The capacitors contribute to stabilizing the latch function by the latch circuit. Therefore, when transistors turn on in response to a serial selection signal at a high level, the latch circuit is prevented from being inverted by the potentials of a serial bus line pair. Accordingly, generation of reading errors is prevented.

A memory chip includes a plurality of pins. The plurality of pins are divided into two rows for arrangement on the opposite sides of the memory chip. All data I/O pins are arranged on one side surface (in the same row) of a package. In the case of forming a memory module, each chip is arranged such that the data I/O pins may be nearest to a center line of a module substrate parallel to a connect pin group. Thereby, interconnections between the respective memory chips and the connect pins have substantially equal lengths.
