Abstract
A content addressable memory circuit comprising: a memory device array including multiple memory devices coupled for simultaneous access to memory address locations that share a common memory address; multiple virtual modules (VMs), wherein each VM stores a data set that includes key values stored within an assigned memory address range within the memory array that are assigned to the VM; wherein each VM, stores a virtual hash table in non-transitory memory, that associates hash values with memory addresses within an assigned memory address range of the VM; hash logic is operable to determine a hash value, based upon a received key value and a respective assigned memory address range; and memory controller logic is operable to use a virtual hash table to access a memory address in an assigned memory address range, based upon the determined hash value.
