Abstract: A system on chip (SOC) includes a slave device, a plurality of master devices, an interconnect device and a plurality of service controllers. The master devices generate requests to demand services from the slave device. The interconnect device is coupled to the slave device and the master devices through respective channels, and the interconnect device performs an arbitrating operation on the requests. The service controllers control request flows from the master devices adaptively depending on an operational environment change of the SOC.

Abstract: In one example embodiment, a memory system includes a memory module and a memory controller. The memory module is configured generate density information of the memory module based on a number of the bad pages of the memory module, the bad pages being pages that have a fault. The memory controller is configured to map a continuous physical address to a dynamic random access memory (dram) address of the memory module based on the density information received from the memory module.

Abstract: A method for executing a virtual machine (VM) in an electronic device is provided. The method includes obtaining a position of a first base disk image stored in a disk image storage, creating a root disk image that backs the first base disk image based on the obtained position, and executing the VM based on the created root disk image. The method further includes, in the run-time of the VM, changing the first base disk to the second base disk, and continuing the VM based on the merged root disk.

Abstract: In one embodiment, the memory device includes at least one memory bank including first and second subbanks, and control logic configured to control storing data into the memory bank. The control logic is configured to activate the first subbank and to precharge the second subbank in response to a first activate command for the first subbank.

Abstract: Disclosed is a network-on-chip system including an active memory processor for processing increased communication latency by multiple processors and memories. The network-on-chip system includes a plurality of processing elements that request to perform an active memory operation for a predetermined operation from a shared memory to reduce access latency of the shared memory, and an active memory processor connected to the processing elements through a network, storing codes for processing custom transaction in request to the active memory operation, performing an operation addresses or data stored in a shared cache memory or the shared memory based on the codes and transmitting the performed operation result to the processing elements.
