Abstract
Disclosed herein are techniques for implementing hybrid memory modules with improved inter-memory data transmission paths. The claimed embodiments address the problem of implementing a hybrid memory module that exhibits improved transmission latencies and power consumption when transmitting data between DRAM devices and NVM devices (e.g., flash devices) during data backup and data restore operations. Some embodiments are directed to approaches for providing a direct data transmission path coupling a non-volatile memory controller and the DRAM devices to transmit data between the DRAM devices and the flash devices. In one or more embodiments, the DRAM devices can be port switched devices, with a first port coupled to the data buffers and a second port coupled to the direct data transmission path. Further, in one or more embodiments, such data buffers can be disabled when transmitting data between the DRAM devices and the flash devices.
