Embodiment Construction

[0041] As used throughout the specification of this application, including the appended claims, the term "coupled (or connected)" may refer to any direct or indirect connecting means. For example, if the text describes that a first device is coupled (or connected) to a second device, it should be interpreted that the first device may be directly connected to the second device, or that the first device may be indirectly connected through other devices or some connecting means to connect to a second device. References to the terms "first", "second" and similar terms throughout the specification of this application (including the appended claims) are only used to name discrete elements or to distinguish different embodiments or ranges. Therefore, the terms should not be regarded as limiting the upper or lower limit of the number of elements and should not be used to limit the arrangement order of the elements. In addition, where possible, elements / components / steps using the same...

Abstract

The invention provides a memory module without a controller and a built-in power supply and a memory controller thereof. The memory module includes a connection portion, a first non-volatile memory chip, and a second non-volatile memory chip. The memory controller of the motherboard accesses the first non-volatile memory chip from the local interface of the first non-volatile memory chip through the connection portion. The second non-volatile memory chip is configured to store at least one pointer of metadata of the first non-volatile memory chip. A memory type of the second non-volatile memory chip is different from a memory type of the first non-volatile memory chip. The memory controller accesses the pointer stored in the second non-volatile memory chip through the connection portion.

Description

technical field [0001] The present disclosure relates to hosts housing random access memory modules; in particular, the present disclosure relates to memory modules and memory controllers. Background technique [0002] Currently, nonvolatile random access memory modules manage the operation of multiple nonvolatile memory chips through a controller on the nonvolatile random access memory module. With the trend of increasing memory capacity, controllers on non-volatile random access memory modules cause heat dissipation problems during the management of larger numbers of memory chips. In addition, based on a double data rate (DDR) interface (such as the OPTANE DIMM interface of INTEL or the NVDIMM interface of SNIA), the existing non-volatile random access memory module is connected to the motherboard of the host. However, since the local interface of the nonvolatile memory chip is not a DDR interface, the controller on the nonvolatile random access memory module needs to per...
