20130275785 | MEMORY CONTROL APPARATUS, MEMORY CONTROL METHOD, INFORMATION PROCESSING APPARATUS AND PROGRAM - There is provided a memory control apparatus including a deciding unit deciding, among a first main storage apparatus that is a main storage apparatus with low power consumption and a second main storage apparatus with power consumption higher than the power consumption of the first main storage apparatus as memory devices of multiple CPU cores, whether the second main storage apparatus is capable of being suspended, and a power managing unit suppressing a power supplied to the second main storage apparatus and at least one of the multiple CPU cores in a case where the deciding unit decides that the second main storage apparatus is capable of being suspended. | 10-17-2013 |
20130332661 | INFORMATION PROCESSING APPARATUS AND METHOD AND PROGRAM - There is provided an information processing apparatus including a rewrite frequency management section configured to manage a rewrite frequency of a page included in a nonvolatile primary storage apparatus having an upper limit in the rewrite frequency, and a data processing section configured, when an instruction for writing write data to a predetermined page is issued and a rewrite frequency of the predetermined page reaches a threshold value that is less than the upper limit of the rewrite frequency of the primary storage apparatus, to write the write data to another page different from the predetermined page, the other page storing no effective data and having a rewrite frequency that does not reach the threshold value. | 12-12-2013 |
20130332662 | INFORMATION PROCESSING APPARATUS AND METHOD AND PROGRAM - There is provided an information processing apparatus including a table saving unit configured to copy an address conversion table stored in a first storage area of a memory to a storage area other than the first storage area and save the copied address conversion table, a table recovery unit configured to recover the address conversion table of a saving time point by copying the saved address conversion table to the first storage area of the memory, and a rewrite control unit configured to, when there is a rewrite request for data of a virtual address associated with a physical address on the address conversion table after the address conversion table has been saved, change the physical address associated with the virtual address, and cause the rewritten data to be stored in a storage area corresponding to the changed physical address. | 12-12-2013 |
20130332695 | INFORMATION PROCESSING APPARATUS AND METHOD AND COMPUTER-READABLE MEDIUM - There is provided an information processing apparatus including a primary storage apparatus configured by combining a plurality of memories each having a different upper limit of a number of possible rewrites, and an allocation management section configured to allocate a storage area of data to be stored in the primary storage apparatus to one of the plurality of memories based on a rewrite frequency of the data. | 12-12-2013 |
20140201601 | INFORMATION PROCESSING DEVICE AND METHOD, AND RECORDING MEDIUM - The present technology relates to an information processing device and method, and a recording medium, which make it possible for a data recording system and so forth to be optimized in accordance with use. Provided are: a recording system decision unit that, on the basis of characteristics which are characteristics of data to be recorded in a recording medium, and include a lifespan value representing the retention period of the data and an error rate representing the percentage of errors assumed to be generated when the data is read, generates a plurality of recording regions of a logical device configured from the recording medium, and also decides recording systems to be applied in each of the recording regions; and a logical device initialization unit that initializes each of the recording regions of the logical device on the basis of the decided recording systems. | 07-17-2014 |
