In one aspect, an apparatus includes a memory repair controller coupled to a memory. The memory repair controller may be configured to provide repair information to cause the memory to disable one or more faulty locations in the memory, and the memory repair controller can be disabled after providing the repair information.

Disclosed are systems and methods by which a storage device may process and return I/O commands to a host in the order in which the host provided the commands, thereby reducing host overhead, including but not limited to the following: receiving a first I/O command and a second I/O command, the first I/O command and the second I/O command being assigned a sequence tag, issuing the first I/O command and the second I/O command to one or more storage channels based on their respective sequence tags, collecting a command completion notice of the first I/O command or the second I/O command when the first I/O command or the second I/O command has been respectively completed; and issuing a command completion notification to a host based on the sequence tag of the associated completed first I/O command or the second I/O command.

A memory system has a memory, a first substrate on which the memory is mounted and which is set to a temperature of −40[° C.] or lower, a controller configured to control the memory; and a second substrate on which the controller is mounted, which is set to a temperature of −40[° C.] or higher, and which transmits and receives a signal to and from the first substrate via a signal transmission cable.

A control method for a solid state drive is provided. The solid state drive includes a non-volatile memory with plural blocks. In a step (a1), a block is opened. In a step (a2), a program action is performed to store a valid write data into the open block. Then, a step (a3) is performed to judge whether an amount of the valid write data in the open block reaches a predetermined capacity. In a step (a4), if the amount of the valid write data in the open block does not reach the predetermined capacity, the step (a2) is performed again. In a step (a5), if the amount of the valid write data in the open block reaches the predetermined capacity, the open block is closed and the step (a1) is performed again. The predetermined capacity is lower than a capacity of one block.

The present disclosure relates to method for checking the reading phase of a non-volatile memory device including at least an array of memory cells and with associated decoding and sensing circuitry and a memory controller, the method comprises: storing in a dummy row associated to said memory block at least internal block variables and a known pattern; performing a reading of said dummy row; comparing a result of the reading with the known pattern; trimming the parameters of the reading and/or swapping the used memory block based on the result of the comparing.

A data access method performed by a processing device is disclosed. The processing device manages a storage device based on a log-structured file system (LFS), where the processing device writes a target file to the storage device based on an out place update (OPU) mechanism; and the processing device writes file attribute information corresponding to the target file in the storage device to out of band (OOB) data of the storage device, to restore, after abnormal power-off, access to the target file by using the file attribute information stored in the OOB data. In this way, when writing the target file to the storage device, the processing device may write a file attribute corresponding to the target file to the OOB data, so that after abnormal power-off, access to the target file may be restored by using the file attribute information.

A storage device and an operating method thereof are provided. The storage device includes a non-volatile memory, an interconnect, a device controller and a buffer memory. The interconnect exchanges data with a host, receives a logging target setting request and a logging period setting request with respect to debugging information from the host, receives a debugging information logging request from the host, and receive a read request from the host. The device controller includes a buffer memory and controls the non-volatile memory, controls a logging operation on the debugging information based on a logging target and a logging period, which are requested by the host, in response to the debugging information logging request, and transmits the debugging information to the host in response to the read request. The device controller is further configured to logs the debugging information in the buffer memory according to the debugging information logging request.

A single input/output (I/O) controller for both secure partitionable endpoints (PEs) and non-secure PEs is enabled in a trusted execution environment (TEE) where secure memory portions are isolated from non-secure PEs. Security attributes for certain endpoints indicate secure memory access privilege of owning entities of the certain endpoints. A security monitor has exclusive access to the address translation control tables (TCE) stored in secure memory associated with a secure endpoint. When owning entity reassignment occurs, the endpoints are reinitialized to support a change in ownership from an outgoing owning entity having secure memory access and an incoming owning entity not having secure memory access.

Various implementations described herein relate to systems and methods for managing metadata for an atomic write operation, including determining metadata for data, queuing the metadata in an atomic list, in response to determining that atomic commit has occurred, moving the metadata from the atomic list to write lookup lists based on logical information of the data, and determining one of metadata pages of a non-volatile memory for each of the write lookup lists based on the logical information.

Provided are systems, methods, and apparatuses for managing storage device memory. A method can include receiving, from a host, a command for managing the memory; performing, by the storage device, the command on first data stored on the memory via at least one processing element in the storage device to generate second data; and transmitting, by the storage device, third data based on the second data to the host.
