Abstract: Systems and methods for synchronizing write credits between a host device and a media controller of a memory system comprising a non-volatile memory (NVM), wherein the host device is configured to maintain a write credit (WC) counter implemented in a memory controller of the host device. The WC counter tracks and limits the number of outstanding write commands which may be issued to the NVM. The host device may query the memory system to obtain status of the available write buffer space in the media controller, and adjust the WC counter based on any detected errors in the write buffer space reported in metadata of read packets sent from the memory system.

In one aspect, a processor-based system includes a DRAM circuit (e.g., disposed on a common x4/x8 die) providing 4-bit-wide data access (“x4”) and a 128-bit internal data prefetch.

The DRAM circuit receives a memory read request from a memory controller communicatively coupled to the DRAM circuit, prefetches 128 bits of data, and returns all of the 128 bits of fetched data to the memory controller in response to the memory read request. In some aspects, the DRAM circuit may also receive a memory write command including 128 bits of write data from the memory controller, and write the 128 bits of write data to memory without performing a read/modify/write (RMW) operation.

Abstract: According to various aspects, a memory controller may schedule ZQ commands to periodically calibrate individual memory ranks in a multi-rank memory. The memory controller may schedule a ZQ short command at each ZQ interval and record that the ZQ short command was missed with respect to a memory rank in a self-refresh mode at the ZQ interval. After the missed ZQ short commands reaches a first threshold, a ZQ long command may be scheduled at the next ZQ interval and normal ZQ behavior may resume in the event that the memory rank exits the self-refresh mode and the ZQ long command is executed. However, if the memory rank stays in the self-refresh mode until missed ZQ long commands reaches a second threshold, the memory controller may trigger a ZQ long command once the memory rank exits the self-refresh mode and skip a next ZQ calibration before resuming normal ZQ behavior.
