Systems and methods for scalable shared memory among networked devices comprising IP addressable memory blocks is disclosed. The disclosed systems and methods comprise a communications network, one or more memory lending devices, each comprising one or more allocated and/or available uniformly sized blocks of memory remotely lendable over the communications network, wherein each of the one or more blocks of memory are uniquely addressable over the communications network using an Internet Protocol (IP) destination address. The systems and methods comprise further comprise at least one memory borrowing device comprising one or more remote blocks of memory allocated (loaned) thereto, wherein the at least one memory borrowing device is configured to individually access each of the one or more remote blocks of memory allocated thereto over the communications network using a unique Internet Protocol (IP) destination address.
