    摘要： A data storage device includes a volatile memory device including a first table area storing a first table having a plurality of first unit information, and a nonvolatile memory device including a subtree area and a second table area. The second table area stores sorted string tables (SSTables) of level 0 each including a respective plurality of first unit information. Each first unit information includes a key corresponding to a key-value (KV) command and a namespace identifying a tenant providing that KV command. The second table area and the subtree area form a data structure which can be queried with a key included in a KV command. The subtree area includes a plurality of subtrees respectively corresponding to a plurality of namespaces, each subtree storing an SSTable of level 1 having a plurality of second unit information each having a key related to the corresponding namespace of that subtree.

    摘要： Embodiments of the present disclosure relate to a memory system and an operating method thereof. The memory system may include a first processor and a second processor. The first processor is configured to manage or process a main read count table including a plurality of first read count table entries each corresponding to one of a plurality of super memory blocks. The second processor is configured to manage or process, when an error occurs during an operation of reading data stored in one of the plurality of super memory blocks, a partial read count table including a read count table entry including information on a count of the read operation executed during a recovery operation for the error, and transmit an update message to the first processor for updating the main read count table based on the partial read count table.

    摘要： An application running in a container is able to access files stored on disk via normal file system calls, but in a manner that remains isolated from applications and processes in other containers. In one aspect, a namespace virtualization component is coupled with a copy-on-write component. When an isolated application is accessing a file stored on disk in a read-only manner, the namespace virtualization component and copy-on-write component grant access to the file. But, if the application requests to modify the file, the copy-on-write component intercepts the I/O and effectively creates a copy of the file in a different storage location on disk. The namespace virtualization component is then responsible for hiding the true location of the copy of the file, via namespace mapping.

    摘要： Embodiments disclosed herein generally relate to techniques for zeroing memory in computing systems where access to memory is non-uniform. One embodiment provides a processor which performs an operation including receiving, via a system call, a request to delete a memory region. The operation also includes sorting, after receiving the request, one or more pages of the memory region according to each of the one or more pages associated affinity domain. The operation further includes sending requests to zero the sorted one or more pages to one or more zeroing threads that are attached to the respective affinity domain. The operation further yet includes waiting, after sending the requests, to return to the system caller until a message is received, from the worker threads in each affinity domain, indicating that all the page zeroing requests have been processed.

    摘要： A media distribution system is provided in which a primary means of transport for digital media is through a device with housing shaped as an optical disc and insertable into various current and future optical disc drive devices. Media travels from different digital sources such as a personal media library and other networked resources to embedded memory on the optical disc shaped device via a capable personal computer or electronic device. This media is then able to be presented in the most appropriate format in a number of different types of current and legacy devices with optical drives such as CD audio devices and DVD players.

    摘要： A circuit for reading or writing a RAM includes a shift register coupled to the RAM, a test data input, and a test data output. The circuit further includes a control circuit configured to generate a pulse every N clock cycles, each pulse triggering a RAM access operation transferring data between the shift register and the RAM, N being equal to a data width of the RAM divided by a parallel factor, the parallel factor being a number of pins in either the test data input or the test data output configured for parallel data loading.
