Processor-dependent address translation for host memory buffer

A solid-state drive (SSD) system, comprising:

• a plurality of processors;
• a host memory buffer (HMB) access module, wherein the HMB access module:
• receives a module identifier and a request address associated with an access request;
• and
• determines a translated address based at least in part on the module identifier and the request address, including by accessing at least one translation table that stores address mappings between (1) the plurality of processors in the SSD system and (2) a host memory buffer, wherein each processor in the plurality of processors has a non-overlapping memory space in the host memory buffer;
• and
• a host interface, wherein the host interface performs the access request, including by accessing the host memory buffer using the translated address, wherein the host memory buffer is located in host memory that is external to the SSD system.
