MEMORY ACCESS GATE - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18136250 Titled 'MEMORY ACCESS GATE'

Simplified Explanation

This abstract describes methods, systems, and devices for a memory access gate. It explains that a memory device consists of a controller, memory dice, and a pad for receiving a control signal from an external source. The memory device also includes a switching component that can choose between the externally provided control signal or an internally generated control signal. The controller then sends the selected control signal to a memory die. The memory device can determine whether it is operating in a diagnostic mode or a regular mode and select the control signal accordingly. The abstract mentions that the controller has a secure register, the value of which can affect or control the switching. An authenticated host device can instruct the controller to write a value to the secure register.

Original Abstract Submitted

Methods, systems, and devices for a memory access gate are described. A memory device may include a controller, memory dice, and a pad for receiving an externally provided control signal, such as a chip enable signal. The memory device may include a switching component for selecting the externally provided control signal or an internally generated control signal. The controller may provide the selected control signal to a memory die. The memory device may determine whether it is operating in a first mode or a second mode, and select the externally provided control signal or the internally generated control signal based on the determination. The first mode may be a diagnostic mode in some cases. The controller may include a secure register whose value may impact or control the switching. An authenticated host device may direct the controller to write the value to the secure register.
