US Patent 7584335 Methods and arrangements for hybrid data storage

Embodiments may comprise a hybrid memory controller to facilitate accesses of more than on type of memory device, referred to generally hereafter as a hybrid memory device or hybrid cache device. The hybrid memory controller may include split logic to determine whether to split data of a write request into more than one portion and to store each portion in a different type of data storage device. For example, one embodiment comprises a hybrid memory controller to store data in both SRAM and DRAM devices. The SRAM and DRAM devices may include distinct circuits on a die, distinct dies within a chip, distinct chips on a memory module, distinct memory modules, or the like.
