A storage device includes: a storage controller to receive one or more notifications corresponding to host data transferred from a host device to the storage device over a storage interface; and a response circuit connected to the storage controller, the response circuit to trigger a response to the host device, and including: a first counter to track the one or more notifications, the one or more notifications corresponding to an entirety of the host data such that each of the notifications corresponds to a portion of the host data; a second counter to track one or more acknowledgements received from the storage controller, the one or more acknowledgments corresponding to the one or more notifications such that each of the acknowledgments corresponds to a notification; and a response trigger to select one of the first counter and the second counter to trigger the response to the host device.

Storage device having a configurable command response trigger

A storage device includes: a host interface to receive a host command from a host device over a storage interface; one or more memory translation layers to execute one or more operations associated with the host command to retrieve one or more chunks of data associated with the host command from storage memory; a bitmap circuit including a bitmap to track a constrained order of the one or more chunks of data to be transferred to the host device; and a transfer trigger to trigger a data transfer to the host device for the one or more chunks of data in the constrained order according to a state of one or more bits of the bitmap.

Memory storage device including a configurable data transfer trigger

A storage device includes: one or more logical blocks to store host data received from a host device, the logical blocks having a logical block address (LBA); an LBA range table to store one or more LBA ranges associated with one or more commands received from the host device over a storage interface; and an overlap check circuit to compare an LBA range associated with an active request with the one or more LBA ranges associated with the one or more commands, and to determine an overlap between the LBA range associated with the active request and any of the one or more LBA ranges associated with the one or more commands

Parallel overlap management for commands with overlapping ranges

A system and method for executing instructions in a constrained order. In some embodiments, the method includes: sending by a host, a first instruction, followed by an order-constrained instruction, followed by a second instruction; receiving, by a target, the first instructions, the order-constrained instruction, and the second instruction; and executing, by the target, the first instruction; the order-constrained instruction, after executing the first instruction; and the second instruction, after executing the order-constrained instruction.

System and method for controlling the order of instruction execution by a target device

A method of performing a write operation, the method comprising: comparing a data pattern of a currently received command directing a write operation to data patterns of at least one previously received command; and performing a write operation, based on the currently received command directing the write operation, by writing the data patterns of the at least one previously received command instead of the data pattern of the currently received command when the data pattern of the currently received command directing the write operation is identical to the data patterns of the at least one previously received command

Buffer memory management method and write method using the same

An electronic system includes: an interface control unit configured to receive a write buffer command; a command core, coupled to the interface control unit, configured to execute a firmware update based on the write buffer command; a non-volatile memory array, coupled to the command core, configured to store an image of a primary file system, a secondary file system, a primary firmware, and a secondary firmware; a tightly coupled memory (TCM), coupled to the command core, configured to contain an operating firmware; and a volatile memory, coupled to the interface control unit, configured to store the write buffer command including a product image; wherein: the command core is configured to execute in order: verify the product image, extract an operating firmware executable and a solid state file system (SSFS) update from the product image, copy the operating firmware executable to the secondary firmware and the TCM, restart the operating firmware as the operating firmware executable in the TCM, extract a solid state file system (SSFS) update from the product image, copy the SSFS update to the secondary file system, copy the operating firmware executable to the primary firmware, and copy the SSFS update to the primary file system.

Electronic system with update control mechanism and method of operation thereof

An electronic system includes: an interface control unit to receive a write buffer command; a command core executes a firmware update based on the write buffer command; a non-volatile memory array configured to store an image of a primary file system, a secondary file system, a primary firmware, and a secondary firmware; a TCM configured to contain an operating firmware; and a volatile memory configured to store the write buffer command including a product image; wherein: the command core executes in order: verify the product image, extract an operating firmware executable and a SSFS update from the product image, copy the operating firmware executable to the secondary firmware, restart the operating firmware with the operating firmware executable copied to the TCM, copy the SSFS update to the secondary file system, copy the operating firmware executable to the primary firmware, and copy the SSFS update to the primary file system.
