摘要:
A display medium of the present invention includes first and second substrates, a spacing member and a particle dispersion liquid. The first substrate is transparent to light. The second substrate is opposite to the first substrate and has plural electrodes placed at an interval. The second substrate has a difference between reflectivity of the electrode portions and reflectivity of plural boundary portions between the electrodes with respect to light incident from the first substrate side. The difference is 12 percentage points or less. The spacing member is placed between the first and second substrates at another interval, is transparent to light, and keeps a gap between the first and second substrates. The particle dispersion liquid is filled between the first and second substrates, and includes particles moving in a direction of an electric field formed between the first and second substrates and a dispersion medium.

A semiconductor memory device in which a memory cell array is divided into a plurality of operation blocks and one regular word line is activated simultaneously in each of two or more operation block. In the semiconductor memory device, when a defective regular word line is set for replacement with a spare word line, data is recorded in fuse ROM (read only memory) in the semiconductor memory device such that a regular word line to be replaced and a replacing spare word line are located in the same operation block or not located each in combined operation blocks which are activated simultaneously. This can prevent the simultaneous activation of a regular word line and a spare word line in the same operation block and malfunction of the semiconductor memory device.

A semiconductor memory device having redundant memory selection circuit XRDN which outputs a redundant replacement selection signal for each bank. In a refreshing operation, each redundant decoder XRED only compares an address indicated by row address signal XADD with an address of a defective memory cell stored, without referring to a bank selection signal included in row address signal XADD. Redundant memory cell selection circuit XRDN outputs redundant replacement selection signals XRDNS(A), (B) for respective banks A, B, for indicating a bank in which the replacement is to be performed with a redundant memory cell.

摘要:
A display medium includes a first substrate that is transparent to light, a second substrate, a spacing member, and a particle dispersion liquid. The second substrate is provided to be opposite to the first substrate and has a plurality of electrodes placed at a predetermined interval. The spacing member (i) is placed between the first and second substrates at another interval different from the predetermined interval of the electrodes, (ii) has a first end portion on a first substrate side of the spacing member and a second end portion on a second substrate side of the spacing member. The first end portion is transparent to light. The second end portion has different transparency from the first end portion to reduces a reflection of light incident through the first substrate onto a first substrate side of the spacing member.

摘要:
A semiconductor memory includes a plurality of memory cell arrays each composed of a plurality of memory cells, each of the memory cell arrays including a plurality of main word lines, each of which is composed of a pair of sub-word lines each connected to a plurality of memory cells, means for driving the main word lines, power supply voltage supply line driving means connected to the sub-line lines. When a redundant word line used in place of a specific sub-word line including a defective sense amplifier is activated, the number of the sub-word lines activated when a data input/output is conducted is different from the number of sub-word lines activated in a refreshing operation. When the data input/output is conducted, a replacement of a sub-word line is executed on the basis of the result of a comparison between an externally supplied row address and an internally stored row address. When the refreshing operation is conducted, the replacement of the sub-word line is executed on the basis of an output of an internal refresh address counter and simultaneously with an ordinary refreshing operation.
