A semiconductor dynamic random access memory (DRAM) 300 with a programmable memory refresh counter 345 is presented. The counter 345 permits the specification of portions of the DRAM 300 to be refreshed, saving power and time over DRAMs that refresh the entire memory. The counter 345 may be programmed...http://www.google.de/patents/US6665224?utm_source=gb-gplus-sharePatent US6665224 - Partial refresh for synchronous dynamic random access memory (SDRAM) circuits
