Modulating credit allocations in memory subsystems

A credit controller, the credit controller configured to:

• allocate a respective number of credits to one or more clients of a memory subsystem of a system on chip (SoC), the one or more clients configured to send transaction requests to a memory controller of the memory subsystem for access data in one or more RAMs of the memory subsystem, the memory controller configured to monitor statistics of the transaction requests of the one or more clients, the statistics comprising at least two of a number of page hits in the one or more RAMs, a number of conflicts that require closing a page of the one or more RAMs before another page can be opened, or a respective number of credits allocated to the client;
• receive, from the memory controller and based on the statistics monitored by the memory controller, a signal indicating that the respective number of credits allocated to the one or more clients should be increased or decreased;
• and
• dynamically change, based on the signal, the respective number of credits allocated to the one or more clients.

A method comprising:

• receiving, by a memory controller operably connected to a credit controller, transaction requests from one or more clients to access data of one or more random-access memories (RAMs) associated with the memory controller;
• storing the transaction requests received from the one or more clients in a buffer of the memory controller;
• monitoring, for each client of the one or more clients, statistics of the transaction requests received by the memory controller, the statistics comprising at least two of a number of page hits in the one or more RAMs, a number of conflicts that require closing a page of the one or more RAMs before another page can be opened, or a respective number of credits allocated to the client;
• determining, based on the statistics, whether memory throughput would be increased by increasing or decreasing a respective number of credits allocated to at least one client of the one or more clients;
• and
• generating, based on a determination that the memory throughput would be increased, an output signal, the output signal configured to indicate to the credit controller that the respective number of credits allocated to the at least one client of the one or more clients should be increased or decreased.
