Abstract: Aspects of the present disclosure are directed to a memory sub-system with isothermal cooling of components. A PCB assembly may be secured between a heat spreader and a heat sink that are thermally coupled. The heat sink radiates heat absorbed from both sides of the PCB assembly. By connecting the heat spreader to the heat sink, heat is more effectively transferred from the side of the PCB assembly not directly connected to the heat sink. The PCB assembly may be secured between a top enclosure and a bottom enclosure. The top enclosure and the bottom enclosure may be thermally coupled using a vapor chamber. The vapor chamber pumps heat from a higher-temperature side of the PCB assembly to a lower-temperature side of the PCB assembly. By using the vapor chamber to thermally couple the top and bottom enclosures, creation of hot spots is avoided.

Abstract: Aspects of the present disclosure configure a memory sub-system processor to use a fin stack to improve heat dissipation to improve a data transfer rate. The processor measures temperature of at least one of the processing device or the set of memory components. The processor accesses a reference temperature for controlling data transfer rate between a host and the set of memory components. The processor compares the measured temperature with the reference temperature and, based on the comparison, adjusts the data transfer rate based on comparing the measured temperature with the reference temperature.

Abstract: Example embodiments are directed to an input/output (IO) bracket that may be used in a solid-state drive (SSD), the IO bracket comprises a faceplate and at least one heat pipe coupled to the faceplate that extends horizontally from a surface of the faceplate. The at least one heat pipe is configured to be coupled to a controller of the SSD in order to transfer heat from the controller out of the SSD. By coupling the controller to the heat pipe instead of a main heatsink, the main heatsink can efficiently dissipate heat from remaining components of the SSD.

Abstract: A semiconductor device assembly is provided that includes a cooling system. The semiconductor device assembly includes a semiconductor die assembled onto a substrate. A channel is disposed at a back side of the semiconductor die to enable fluid to flow through the channel and cause heat to transfer from the semiconductor die to the fluid. The fluid is received through an inlet to enable the fluid to be flowed through the channel. After the fluid is flowed through the channel, the fluid is expelled through an outlet. In this way, a compact and effective cooling system for a semiconductor device assembly may be implemented.

Abstract: Aspects of the present disclosure configure a memory sub-system processor to use a triangular shaped metal bracket to improve heat dissipation to improve a data transfer rate. The triangular shaped metal bracket being physically attached to an edge of the PCB at a base portion of the triangular shaped metal bracket. The triangular shaped metal bracket is thermally coupled to the set of memory components and the processing device of the PCB via the base portion along with a heat spreader on a primary and secondary side of the bracket. The triangular shaped metal bracket being configured to dissipate heat from the processing device and the set of memory components to at least a host device through a vertex portion of the triangular shaped metal bracket.

Abstract: Example embodiments are directed to a solid-state drive (SSD) enclosure design that is adaptable for different printed circuit board assemblies (PCBA). The SSD enclosure design comprises a three-piece construction that includes a top enclosure, a bottom enclosure, and an intermediate structure. The bottom enclosure is coupled to the top enclosure to form a housing for a PCBA having NOT AND (NAND) devices and a controller. The intermediate structure is coupled to the PCBA and positioned between the top enclosure and the bottom enclosure within the housing. The intermediate structure comprises a plurality of heatsinks to transfer heat from the NAND devices and a controller heatsink to transfer heat from the controller, whereby the type and location of the heatsinks can be changed for a different PCBA without having to change the top enclosure or bottom enclosure. The top enclosure can include vents that allow air to flow through.

Abstract: Exemplary methods, apparatuses, and systems include an environmental operations manager for controlling memory access of the memory device. The environmental operations manager receives a set of data bits for programming to a memory location. The environmental operations manager receives environmental condition data. The environmental operations manager delays programming of the set of data bits to the memory location and writing the set of data bits to a buffer location in response to determining that the environmental condition data satisfies a threshold.
