Smart in-module refresh for DRAM
Abstract:
A dynamic Random Access Memory (DRAM) module (105) is disclosed. The DRAM module (105) can includes a plurality of banks (205-1, 205-2, 205-3, 205-4) to store data and a refresh engine (115) that can be used to refresh one of the plurality of banks (205-1, 205-2, 205-3, 205-4). The DRAM module (105) can also include a Smart Refresh Component (305) that can advise the refresh engine (115) which bank to refresh using an out-of-order per-bank refresh. The Smart Refresh Component (305) can use a logic (415) to identify a farthest bank in the pending transactions in the transaction queue (430) at the time of refresh.
