Abstract: A method performed by automated test equipment (ATE) includes power cycling a solid state drive (SSD) device under test by the ATE, wherein the SSD device includes a memory controller integrated circuit (IC) attached to a printed circuit board (PCB) having a PCB interface; communicating one or more signals between the ATE and the memory controller IC using the PCB interface in a normal system mode; sending a command to cause the memory controller IC to place the PCB interface in a boundary scan mode; remapping a portion of pins of the PCB interface to a boundary scan interface; and communicating one or more boundary scan signals between the ATE and the memory controller IC using the remapped portion of pins of the PCB interface in the boundary scan mode.

Abstract: A system comprises a testing mode register, a set of pins, and a test access port controller. The test access port controller initiates a first testing mode by configuring the set of pins according to a first pin protocol. The test access port controller configures a first pin to receive first test pattern data based on a first convention and configures a second pin to output first test result data based on the first test pattern data. Based on detecting a register command stored in the testing mode register, the test access port controller initiates a second testing mode by configuring the set of pins according to a second pin protocol. The test access port controller configures the first pin to receive a second test pattern data generated based on a second convention and configures the second pin to output a second test result data based on the second test pattern data.

Abstract: Data traffic comprising data packets communicated between a memory sub-system and a host system is monitored by a processing device at the memory sub-system. Data packets are classified according to packet type. Log data comprising a frequency and latency information associated with each packet type is generated. The log data is stored in a memory component of the memory sub-system.

Abstract: Command execution data is received. The command execution data comprises a block address corresponding to an functional component, a register identifier corresponding to a design for testability (DFT) register of the functional component, and command data. The command execution data is converted to a serial command. The serial command is committed to the DFT register of the functional component. A response to the serial command is received. The response is generated by the functional component based on the serial command. The response is converted to command response data and is provided to a testing sub-system.

Abstract: A system comprises a memory sub-system controller mounted to a printed circuit board (PCB) and an in-circuit test (ICT) device. The memory sub-system controller has test points on the PCB comprising stimulus points and observation points. The ICT device connects to the test points of the controller. The ICT device converts automated test pattern generation (ATPG) input test vectors to test signals. A first set of pin drivers of the ICT device applies the test signals to the stimulus points of the controller and a second set of pin drivers of the ICT device read output signals output at the observation points of the controller. A comparator of the ICT device compares the output signals with output test vectors. The comparator provides test result data comprising a result of the comparison.

Abstract: Boundary scan test data and a command to initiate a boundary scan test are received via a universal asynchronous receiver-transmitter (UART). Based on receiving the command, a boundary scan test mode is initiated at a memory sub-system controller. A boundary scan test vector based on the boundary scan test data is synchronously streamed to a boundary scan chain. Test result data output by the scan chain is provided to a UART host via the UART.
