20110085395 | OUTPUT ENABLE SIGNAL GENERATING CIRCUIT AND METHOD OF SEMICONDUCTOR MEMORY APPARATUS - An output enable signal generating circuit for a semiconductor memory apparatus includes an output control unit configured to receive CAS latency information and to generate an output control signal having enable timing according to a DLL on/off mode, and an output enable signal output unit configured to receive the output control signal and to output an output enable signal in response to a read command and a DLL clock signal. | 2011-04-14 |
20110085396 | REPAIR FUSE DEVICE - A repair fuse device is provided. The repair fuse device remarkably reduces the number of the enable fuse cuttings by making initial states of all repair fuse sets to a repair state, cutting an address fuse corresponding to a defective cell, and cutting an enable fuse corresponding to a defective redundancy cell. | 2011-04-14 |
20110085397 | Semiconductor device and information processing system including the same - A semiconductor device includes plural core chips and an interface chip that controls the plural core chips. Each of the plural core chips includes a layer address generating circuit that generates a second chip address by incrementing a value of a first chip address and a layer address comparing circuit that compares a third chip address supplied from the interface chip and the second chip address, and activates a chip selection signal when the third chip address and the second chip address are matched with each other. When a non-used chip signal is in an inactivated state, the layer address generating circuit supplies the second chip address to another core chip, and when the non-used chip signal is in an activated state, the layer address generating circuit supplies the first chip address to another core chip without a change. | 2011-04-14 |
