HYB4164P2LF

64K x 1-Bit Dynamic RAM (DRAM) chip manufactured by Siemens AG. This high-density volatile memory component provides exactly 65,536 bits of primary storage organized in a single-bit-wide configuration, featuring an optimized low-power layout fabric. It functions by storing binary data as microscopic electrical charges inside internal capacitive storage cells, requiring continuous external memory refresh cycles every few milliseconds combined with multiplexed row and column address strobing to retain data integrity. It was standard infrastructure for expanding system memory arrays inside late-1980s personal computers, telecommunication exchange switches, electronic office typewriters, and early engineering workstations.
