Writing a nonvolatile memory to programmed levels

A fluid dispensing system comprising:

• a support structure to receive a fluid dispensing device comprising a nonvolatile memory and an input to receive a fire signal;
• and
• a controller to:
• set the fluid dispensing device to a memory write mode;
• after setting the fluid dispensing device to the memory write mode:
• activate the fire signal for a first time duration to write a first portion of the nonvolatile memory to a first programmed level, and
• activate the fire signal for a second time duration to write a second portion of the nonvolatile memory to a second programmed level, the second time duration being different from the first time duration, and the second programmed level being different from the first programmed level;
• set the fluid dispensing device to a fluidic operation mode;
• and
• after setting the fluid dispensing device to the fluidic operation mode:
• activate the fire signal to deliver a signal pulse that causes activation of fluidic actuators in the fluid dispensing device to dispense fluid.

A method comprising:

• setting a fluid dispensing device to a fluidic operation mode based on a first input received by the fluid dispensing device during a configuration operation of the fluid dispensing device;
• while the fluid dispensing device is set to the fluidic operation mode, receiving an activation signal pulse delivered by an activation of a control signal at an input of the fluid dispensing device to activate fluidic actuators of the fluid dispensing device;
• setting the fluid dispensing device to a memory write mode based on a second input received by the fluid dispensing device during the configuration operation of the fluid dispensing device, the second input being different from the first input;
• and
• while the fluid dispensing device is set to the memory write mode:
• writing a first portion of a nonvolatile memory of the fluid dispensing device to a first programmed level responsive to the control signal being activated for a first time duration, and
• writing a second portion of the nonvolatile memory to a second programmed level responsive to the control signal being activated for a second time duration different from the first time duration, the second programmed level being different from the first programmed level.
