| 20110161774 | SEMICONDUCTOR MEMORY SYSTEM HAVING ECC CIRCUIT AND METHOD OF CONTROLLING THEREOF - A semiconductor storage system includes: a memory region having a plurality of memory cells; and a memory controller having a data control unit. The data control unit includes a write control unit which, during a write operation, performs first error check correction (ECC) encoding on an input data to generate a first encoded input data, compresses the first encoded input data to generate a compressed input data, and performs second ECC encoding on the compressed input data to generate a second encoded input data. The write control unit then writes the second encoded input data into the memory region as a write data. | 06-30-2011 |
| 20110161611 | METHOD FOR CONTROLLING SEMICONDUCTOR STORAGE SYSTEM CONFIGURED TO MANAGE DUAL MEMORY AREA - A method for controlling a semiconductor storage system configured to manage dual memory areas for protecting the system against abrupt and abnormal power disruptions is presented. The semiconductor storage systems has a first physical area and a second physical area, in which first data having a first logical block address are stored in the first physical area. The method includes providing a write command so that the first data is updated to second data. The method also includes writing the second data in a second physical area in response to the write command. When writing the second data in the second physical area, a corresponding invalid logical address is allocated to the second physical area. | 06-30-2011 |
