PRINT COMPONENT WITH MEMORY CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18448794 titled 'PRINT COMPONENT WITH MEMORY CIRCUIT
Simplified Explanation
The patent application describes a memory circuit for a print component that has multiple I/O pads, including an analog pad, to connect to signal paths for operating signals.
- The memory circuit includes a controllable selector that can disconnect a signal path to the print component.
- It also includes a memory component to store memory values associated with the print component.
- A control circuit is used to operate the controllable selector in response to a sequence of operating signals representing a memory read, blocking the memory read of the print component.
- Instead of the memory read, an analog signal is provided to the analog pad, representing the stored memory values selected by the memory read.
Original Abstract Submitted
A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. The memory circuit includes a controllable selector connected in line with one of the signal paths via the I/O pads, the selector controllable to disconnect the corresponding signal path to the print component, and a memory component to store memory values associated with the print component. A control circuit, in response to a sequence of operating signals received by the I/O pads representing a memory read, to operate the controllable selector to disconnect the signal path to the print component to block the memory read of the print component, and provide an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.
