    摘要: In accordance with one aspect of the present invention, provided is a semiconductor device comprising a semiconductor chip which is directly covered with a resin material having a light shielding property as well as a film which is provided on the resin material for shielding the semiconductor device against light. The film may be formed by a seal having a surface which is covered with a metal and a rear surface which is colored black, a layer of a metal or ceramics which is deposited in a vapor phase, or a coating of an insulating material whose refractive index is different from that of the resin material. In another aspect of the present invention, provided is a semiconductor device which is directly covered with a resin material mixed with a light absorbing material. In still another aspect of the present invention, provided is a semiconductor device comprising a semiconductor chip, having a surface covered with black polyimide, which is further covered with a resin material having a light shielding property. In a further aspect of the present invention, provided is a package for covering a semiconductor device which is mounted on a wiring board. According to such improvement, a light shielding property is improved particularly in relation to a thin semiconductor device whose thickness is only about 1 mm, and the semiconductor device is prevented from a malfunction caused by light.

    摘要: In a cache DRAM including a DRAM memory array and a SRAM memory array provided on the same chip, a plurality of pairs of MOS transistors are provided, as block transfer gates, so as to connect bit line pairs in the DRAM memory array and bit line pairs in the SRAM memory array one pair by one pair, and a data transfer amount controlling circuit for controlling the plurality of pairs of MOS transistors, a block including a predetermined number of pairs at a time, is newly provided. Data transfer amount controlling circuit is constructed to simultaneously turn on only pairs of MOS transistors included in blocks of a number in accordance with a predetermined external signal out of the plurality of pairs of MOS transistors. Therefore, the amount of data transferred at a time between the DRAM memory array and the SRAM memory array can be changed by changing the combination of the logical levels of external signals.
