A data processing apparatus which saves data in a volatile memory into a nonvolatile memory when power is off, the data processing apparatus including:

Data processing apparatus and program

A memory apparatus including: a cache control section to control a cache memory for an auxiliary storage apparatus; a volatile memory; and a nonvolatile memory, wherein the cache memory for the auxiliary storage apparatus is configured to have a volatile cache memory provided in the volatile memory and a nonvolatile cache memory provided in the nonvolatile memory, and wherein the cache control section accesses the nonvolatile cache memory using a write back method.

Memory apparatus, cache control method, and cache control program

An information processing apparatus including: a nonvolatile memory; a volatile system memory in which predetermined data stored in the nonvolatile memory is developed; a control section to save the predetermined data stored in the system memory in the nonvolatile memory when a start of power-off operation is detected; and a storage section that stores a first timing information representing a time point of terminating the operation of saving the predetermined data in the nonvolatile memory, and a second timing information representing a power-off time point, wherein the control section compares the first timing information stored in the storage section with the second timing information, subsequent to the next operation of turning on of the power.

Verifying the validity of data saved at power down by comparing the time of save to time of power-off upon start up

An image forming apparatus includes: an image reading device for reading an image of a document to obtain image data; a data communication device connected with a computer for receiving an image data from the computer; a facsimile device connected with a telephone line for receiving an image data through the telephone line; an image memory for storing the image data obtained through the image reading device, the image data obtained through the data communication device, and the image data obtained through the facsimile device; an image memory controller for mediating an access to the image memory in a predetermined priority order for storing and reading the image data among the image reading device, the data communication device, and the facsimile device; and an image forming device for forming the image according to the image data controlled by the image memory controller.
