The Mac Mini M4 integrates its LPDDR5X memory directly into the chip package

Apple’s M4 Mac Mini uses unified memory — LPDDR5X that’s built into the chip package and shared between the CPU and GPU. That means no upgrade slots, no SO-DIMMs, no user-serviceable RAM. Whatever you configure at purchase is what you get for the life of the machine. The upside: the tight integration gives the GPU fast access to the same memory pool, which is why Apple Silicon machines handle creative workloads so well.
