Abstract

Systems and methods are described for network address lookup entry aging in a DRAM memory. A method of DRAM data aging includes: refreshing a row of memory cells in an array of DRAM memory cells. The refreshing periodically includes aging all entries that are stored in the row of memory cells. The systems and methods provide advantages in that an existing operation is used for an additional function. In addition, the aging can be implemented with closely coupled logic using the sense amplifiers.
