摘要： A current problem is that when a DRAM is to be accessed through a data bus, the DRAM is accessed independently of a bank, a row address, etc., and therefore, is inefficient. To solve this problem, an address bus and a data bus are connected to a main memory part independently of each other, a temporary memory part for holding a plurality of addresses in advance is disposed on the address bus side and holds addresses for every access to the main memory part regardless of transfer of data, thereby pipelining address inputting cycles. Further, for the purpose of an effective operation of the main memory part, using the addresses which are held, the addresses are rearranged in such a manner that addresses with the same row addresses become continuous to each other, or when there are not addresses with the same row addresses, addresses different banks from each other become continuous to each other, and the memory is thereafter accessed. This reduces the number of precharges, shortens a standby period which is necessary for a precharge, and realizes accessing while reducing a wasteful use of time.
摘要翻译：目前的问题在于，当通过数据总线访问DRAM时，独立于存储体，行地址等访问DRAM，因此是低效的。为了解决这个问题，地址总线和数据总线彼此独立地连接到主存储器部分，预先存储多个地址的临时存储器部分设置在地址总线侧，并且保存地址以进行每次访问主存储部分不管数据传输，从而流水线地址输入周期。此外，为了主存储器部分的有效操作，使用所保存的地址，地址被重新排列，使得具有相同行地址的地址彼此连续，或者当没有地址与相同的行地址，彼此不同的存储体彼此变得连续，并且此后访问存储器。这减少了预充电次数，缩短了预充电所需的待机时间，并实现了访问，同时减少了浪费时间的使用。

摘要： A power-saving network unit, which is connected to a network made up of a plurality of power-saving network units, includes: network monitoring means; network information memory; power-saving mode setting means; peripheral I/O interface; and digital processor. The network monitoring means monitors a topology of the network, or the interconnection relationship among the power-saving network units. Every time the network has been modified, the network monitoring means stores the modified network topology on the network information memory. The power-saving mode setting means receives the network information stored on the network information memory. If the power-saving network unit is a master or relay node in the network, then the power-saving mode setting means locks the peripheral I/O interface and digital processor of the power-saving network unit to the normal operation mode and prohibits these sections from entering the power-saving mode.

摘要： A data line pair and a strobe line pair are provided between first and second chips to exchange data therebetween. The first chip includes an output circuit and a controller for controlling the output circuit. The second chip includes an input circuit. For example, the output circuit supplies a direct current from a power supply to one of the data lines. Then, the input circuit feeds back the received current to the output circuit through a pair of terminal resistors and the other data line. Subsequently, the output circuit supplies the fed back direct current to one of the strobe lines. In response, the input circuit feeds back the received current again to the output circuit through another pair of terminal resistors and the other strobe line. And then the fed back current is drained to the ground. Thus, compared to driving the data and strobe line pairs separately with the same amount of current supplied, the current dissipation can be halved. In this manner, the present invention is applicable to reduction of current dissipation when data should be transmitted at high speeds through multiple data bus pairs that are driven with a current supplied.

摘要： A voltage control circuit for implementing, e.g., the CPS function in which a high-accuracy comparison is performed between a high external voltage and a reference voltage. A diode-connected transistor converts the external voltage to a voltage lower than the external voltage in conjunction with an external voltage dropping resistor. A comparator compares the converted voltage with a specified comparison voltage. The size of the transistor is determined such that the ratio of an increment of the converted voltage to an increment of the external voltage is sufficiently high in a comparison region in which the external voltage is close to the reference voltage. A clamping circuit clamps the converted voltage with a specified limit voltage such that the converted voltage does not exceed the withstand voltage of the circuit.
