Processing-in-memory memory device and method for performing indirect addressing in the same

A method of performing an indirect addressing mode in a processing-in-memory (PIM) memory device comprising a memory bank including a memory array and a PIM engine configured to directly execute processing-in-memory according to a PIM instruction, and a PIM control unit configured to control the memory bank, the method comprising:

• identifying, by a request identification unit of the PIM control unit, the PIM instruction by inspecting a request incoming from a memory controller;
• decoding, by an instruction decoding unit of the PIM control unit, the identified PIM instruction, to
• extract a control signal, an operand, and a target address, and
• extract and store an indirect address use signal and a data path for calculating an indirect address;
• storing, by at least one control register of the PIM control unit,
• the extracted control signal as Ropcode, and
• the target address as Raddr;
• and
• receiving, by an effective address generation unit of the PIM control unit, the indirect address use signal from the instruction decoding unit;
• and
• generating, by an effective address generation unit of the PIM control unit, an indirect address by
• using the Raddr as a base register value, and
• using an immediate value in the PIM instruction, a register value of the PIM engine, or a data value of the memory bank as an offset value.
