Abstract
A memory controller can receive transactions from an interconnect to access the memory. The memory controller can use a credit-based scheme to request the interconnect to send specific memory transactions that can be scheduled in a desirable order using a credit type associated with each transaction. In some embodiments, the memory controller can keep track of the number of transactions directed to each bank of the memory based on a credit type, so that specific transactions directed towards the underutilized banks can be requested and scheduled in a manner to utilize all the banks more uniformly to improve the system performance.
