Electrical storage device for a replaceable printing component

A replaceable printing component for an ink-jet printing system having at least one replaceable component, the replaceable component including an electrical storage device responsive to printing system control signals for transferring information between the printing component and the ink-jet printing system, the replaceable printing component comprising:

• a write once electrical storage portion, the write once portion responsive to only a first occurrence of write control signals for storing information provided to the write once electrical storage portion;
• a non-protected electrical storage portion responsive to write control signals for storing information provided to the non-protected electrical storage portion;
• and
• a protected electrical storage portion having a protected state in response to an occurrence of a write protect active signal and a non-protected state, wherein the protected electrical storage device in the non-protected state is responsive to write control signals for storing information provided to the protected electrical storage portion, and wherein the protected electrical storage device in the protected state preventing storage of information in the protected electrical storage portion, and wherein the write once, protected and non-protected electrical storage portions are responsive to read control signals for transferring information stored in the write once, protected and non-protected electrical storage portions, respectively, to the ink-jet printing system.

An ink-jet printing system for selectively depositing ink on print media, the ink-jet printing system comprising:

• a replaceable printing component of the type having an electrical storage device associated therewith, the electrical storage device including:
• a non-protected electrical storage portion responsive to write control signals for storing information provided to the non-protected electrical storage portion;
• and
• a protected electrical storage portion having a protected state in response to an occurrence of a write protect active signal and a non-protected state, wherein the protected electrical storage device in the non-protected state is responsive to write control signals for storing information provided to the protected electrical storage portion, and wherein the protected electrical storage device in the protected state preventing storage of information in the protected electrical storage portion;
• and
• a printer portion configured for receiving the replaceable printing component and establishing electrical connection therewith, the printer portion selectively providing read control signals for transferring information stored in the protected and non-protected electrical storage portions, respectively, to the printer portion and write control signal for selectively transferring information between the printer portion and the electrical storage device, wherein the printer portion selectively providing the write protect active signal to preserve data integrity within the protected electrical storage device.
