MEMORY ACCESS GATE: abstract simplified (18136250)

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

Simplified Explanation

The abstract describes a memory access gate system that includes a memory device with a controller, memory dice, and a pad for receiving a control signal. The memory device can switch between an externally provided control signal and an internally generated control signal. The controller determines the operating mode of the memory device and selects the appropriate control signal. The first mode may be a diagnostic mode, and the controller includes a secure register that can be controlled by an authenticated host device.

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.
