Abstract:
1. A recording apparatus characterized by having a memory access controlling section between an apparatus main body controlling section provided in a recording apparatus main body and a non-volatile memory provided in a recording material accommodating cartridge, in order to control writes to and readouts from said non-volatile memory based on commands supplied by said apparatus main body controlling section, said memory access controlling section adapted to receive a mode set command from the apparatus main body controlling section and operable to store an operation mode embodied in the mode set command in a mode register, said memory access controlling section having a random access memory for temporarily storing data read out from said non-volatile memory, such that when said memory access controlling section receives a memory access controlling operation mode command from said apparatus main body controlling section, said apparatus main body controlling section causes data stored in said non-volatile memory to be transferred to said random access memory, causes various processes to be executed by referencing the data stored in said random access memory to update the data stored in said random access memory, and then causes the data stored in said random access memory to be transferred to said non-volatile memory.
