Abstract
Memory system controllers can include hardware masters, first buffers, and a switch coupled to the hardware masters and to the first buffers. The switch can include second buffers and a buffer allocation management (BAM) circuit. The BAM circuit can include a buffer tag pool. The buffer tag pool can include tags, each identifying a respective first buffer or a respective second buffer. The BAM circuit can be configured to allocate a tag to a hardware master in response to an allocation request from the hardware masters. The BAM circuit can be configured to prioritize allocation of a tag identifying a second buffer over a tag identifying a first buffer.
