Abstract: A method can include receiving, at a serial input/output (IO) of a memory device, at least command values, address values and metadata that includes an encoded length value in synchronism with a serial clock. From at least the command, address and encoded length values, a memory access operation, a memory array location, and one of a plurality of different data length values (LEN) corresponding to the memory access operation can be determined. At least data having a length corresponding to the one of the plurality of different LEN can be transferred at the serial IO in synchronism with the serial clock during execution of the memory access operation. Corresponding devices and systems are also disclosed.

Abstract: A method can include, in an integrated circuit device: at a unidirectional command-address (CA) bus having no more than four parallel inputs, receiving a sequence of no less than three command value portions; latching each command value portion in synchronism with rising edges of a timing clock; determining an input command from the sequence of no less than three command value portions; executing the input command in the integrated circuit device; and on a bi-directional data bus having no more than six data input/outputs (IOs), outputting and inputting sequences of data values in synchronism with rising and falling edges of the timing clock. Corresponding devices and systems are also disclosed.

Abstract: A non-volatile memory (NVM) integrated circuit device includes an NVM array of memory cells partitioned into a first physical region to store a first firmware stack and a second physical region to store a second firmware stack. The NVM integrated circuit device also includes a processing device that enables a host microcontroller to execute in place the first firmware stack stored within a first set of logical addresses that is mapped to the first physical region. The processing device tracks accesses, by the host microcontroller, to the first set of logical addresses. The processing device, in response to detecting one of a certain number or a certain type of the accesses by the host microcontroller, initiates a recovery operation including to remap the first set of logical addresses to the second physical region.

Abstract: An apparatus including non-volatile memory to store a forensic key and data, the data received from a host computing system. A processing device is coupled to the non-volatile memory and is to: allow writing the data, by the host computing system, to a region of the non-volatile memory; in response to a lock signal received from the host computing system, assert a lock on the region of the non-volatile memory, the lock to cause a restriction on access to the region of the non-volatile memory by an external device; and provide unrestricted access, by the external device, to the region of the non-volatile memory in response to verification of the forensic key received from the external device.
