The present application provides a memory device. The memory device includes a connector plate having a front edge and a rear edge opposite to the front edge, wherein the connector plate comprises an edge connector disposed at the rear edge and configured to connect to a host connector of a host device; a controller plate defining a first connection region, a second connection region and a chip region, wherein the controller plate is attached to the connector plate at the first connection region, and the controller plate comprises a memory control module disposed in the chip region and in electrical communication with the edge connector; and at least one memory module detachably connected to the controller plate at the second connection region of the controller plate, wherein each of the at least one memory module is in electrical communication with the memory control module when the memory module is connected to the controller plate, such that the memory module can be accessible by the host device via the memory control module.

Modular memory devices

A memory device with modular design and the memory system comprising the same is disclosed. The memory device comprises a substrate plate having a front edge, a rear edge opposite to the front edge, and a top side and a bottom side which are opposite to each other and extend between the front edge and the rear edge; an edge connector positioned at the rear edge and configured to connect to a host connector of a host device; a memory control module positioned on one of the top side and the bottom side of the substrate plate; at least one socket positioned on the top side of the substrate plate and configured to connect to at least one removable memory module; and wherein the memory controller module is electrically coupled to the edge connector and the at least one socket such that the at least one memory module can be accessible by the host device via the memory control module.

Memory device with modular design and memory system comprising the same

An apparatus for controlling access to a memory device comprising rows of memory units is provided. The apparatus comprises: an operation monitor configured to track memory operations to the rows of memory units of the memory device; a row hammer counter configured to determining, for each of the rows of memory units, row hammer effects experienced by the row of memory units due to the memory operations to the other rows of memory units of the memory device; a mitigation module configured to initiate, for each of the rows of memory units, row hammer mitigation in case that accumulated row hammer effects experienced by the row of memory units reach a predetermined threshold; and a virtual host module configured to perform the row hammer mitigation targeting a row of memory units in response to the initiation of row hammer mitigation for the row of memory units by the mitigation module.
