Abstract: Various embodiments described herein use a set of capacitor sets (e.g., capacitor banks) in a power backup architecture for a memory sub-system, where each capacitor set can be individually checked for a health condition (e.g., in parallel) to determine their respective health after the memory sub-system has completed a boot process. In response to determining that at least one capacitor set has failed the health condition (or a certain number of capacitor sets have failed the health condition), the memory sub-system can perform certain operations prior to primary power loss to the memory sub-system (e.g., preemptively performs a data backup process to ensure data integrity) and can adjust the operational mode of the memory sub-system (e.g., switch it from read-write mode to read-only mode).

Abstract: A power management integrated circuit (PMIC) is described for providing system management bus (SMB) isolation, along with memory sub-systems which include such a PMIC and methods of operating such devices. In one embodiment, a PMIC comprises a voltage supply input, power management circuitry, and elements of a SMB. The SMB elements can include an SMB input, an SMB hot swap controller coupled to the SMB input, one or more SMBs, and one or more SMB outputs. When integrated with a memory sub-system, one SMB output can be connected to a memory controller and another SMB output to a microcontroller. During different power states (e.g., normal or low power states), certain outputs can be isolated in order to manage communications on the SMB during the different power states of the memory sub-system using the PMIC.
