Abstract: The present disclosure provides methods for copying a data page in a flash memory device using a flash memory controller. A method may comprise receiving, at the host flash controller, a copy command from a host processor, in response to the copy command, transmitting a read command to the unmanaged flash memory storage device via a bus, wherein the read command indicates particular data, receiving the particular data from the unmanaged flash memory storage device via the bus, storing the particular data in a data buffer included in the host flash controller, and transmitting to the unmanaged flash memory storage device, via the bus, a write command to write the particular data.

Abstract: A computing device and method for managing file access control policies on a computing device are disclosed. The method includes maintaining file-access policies in user space, receiving, at a kernel level, from a user in user space, a request to access a file, and directing the request from the kernel level to a file-policy manager in user space. At least one of the of the file-access policies is enforced in user space with the file-policy manager to grant or deny access to the file, and file operations are performed on the file using only kernel-level calls when access to the to the file is granted.

Abstract: A method and apparatus for refreshing flash memory are disclosed herein. The method includes allocating a different and increasing sequence number to each of a plurality of physical blocks of the flash memory and storing each of the sequence numbers in connection with each of a corresponding one of the physical blocks in non-volatile memory. A refresh-sequence number equal to the highest sequence number in the non-volatile memory is also stored, and in response to a refresh trigger, data in each of the physical blocks that has a sequence number less than the refresh-sequence number is copied to a corresponding one of a plurality of new physical blocks. A new sequence number is then allocated to each of the new physical blocks.

Abstract: In some embodiments a device for data transfer is provided. A device for data transfer is provided. The device comprises an electronic hardware processor. The electronic hardware processor is configured to generate a Trivial File Transfer Protocol (TFTP) Read Request (RRQ) packet requesting transfer of a file. The RRQ packet includes a parameter indicating that transmission of TFTP acknowledgement (ACK) packets are deferred until the electronic hardware processor receives the entire file. The electronic hardware processor is further configured to generate a TFTP ACK packet in response to receiving the entire file.
