Abstract: A function extending apparatus for receiving a portable computer is disclosed. The function extending apparatus includes an AC/DC adapter, a second charging system and a controller. The AC/DC adapter is capable of supplying power to the portable computer equipped with a system load and a first charging system having a first charger and a first battery. The second charging system of the function extending apparatus includes a second charger and a second battery. The controller reduces power consumption of the second charging system when the output power of the AC/DC adapter reaches a first threshold value. The controller reduces power consumption of the first charging system when the output power of the AC/DC adapter reaches a second threshold value, wherein the second threshold value is higher than the first threshold value.

Abstract: A method for controlling a charging system having multiple loads is disclosed. Power is supplied from an AC/DC adapter to a first charger, a second charger, and system loads. The first charger is operated at a setting value having smaller power consumption than a setting value necessary for a first battery pack when output power of a power source reaches a first threshold value during a time when the first battery pack is required to be charged in a standard charging mode. The first charger is operated at a setting value according to a specific charging mode even when the output power of the power source reaches the first threshold value during a time when the first battery pack is required to be charged in the specific charging mode. A second charger is operated at a setting value having smaller power consumption than a setting value necessary for a second battery pack when the output power of the power source reaches a second threshold value larger than the first threshold value.

Abstract: A memory device to perform a plurality of data transfers during a single memory cycle without extending the cycle time for memory access, and to enhance the data transfer rate.A memory array 1 has a plurality of word lines, a plurality of bit lines divided into a predetermined number of groups, and a plurality of memory cells. The bit lines are grouped based on a residue obtained by dividing a column address designating a bit line by the number of groups. The column address decoder 4 generates column addresses of the group number in accordance with the column address signal and an access order signal designating the access order for the groups. When the access order signal designates the ascending order, the bit line selection means 3 generates sequential column addresses, in a number equivalent to the group number and in the ascending order, with the column address signal serving as a reference.

Abstract: A DRAM system having two data stored in continuous addresses that are fetched to improve the data transfer rate in a memory system. An output signal indicating shift up or shift down is added to a predecoder to supply to a decoder. The decoder receives this signal, and enables it to access a block higher or lower than a block corresponding to an address designated by the input address. Specifically, a line is arranged to a block adjacent to one block so that this line can be activated by a shift-up signal or the like.
