HBM4 memory controller
Maturity plannedTargets FPGA + ASICDifficulty Very hardPriority 2
HBM4 controller for the 2048-bit interface with 32 channels, directed refresh management and per-channel scheduling.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
