拆解一颗苏联时代的芯片

Core Viewpoint - The article discusses the disassembly and analysis of the K565PY3 chip, a Soviet-era DRAM chip that is a reverse-engineered clone of Intel's 4116 DRAM chip, highlighting its historical significance and technical details [2][9]. Group 1: Chip Analysis - The K565PY3 chip is a 16KB dynamic random access memory (DRAM) chip believed to have originated from a factory in present-day Moldova [2]. - The chip features a robust "fish can" structure, which was examined using various microscopy techniques to reveal its internal architecture [5]. - The internal structure consists of a 128 x 128 memory cell matrix, with further analysis showing details related to CAS (Column Address Strobe) and RAS (Row Address Strobe) functionalities, which are critical for memory performance [7]. Group 2: Historical Context - The K565PY3 is identified as a clone of the Intel 4116 DRAM chip, which was popular in the late 1970s and early 1980s, used in iconic computers like Apple II and IBM PC [9][10]. - The chip likely originated from Soviet home computers, which were often clones of Western technology, and was also utilized in embedded systems and industrial electronics in the Soviet Union [10]. - The reverse engineering of the K565PY3 is speculated to be based on samples from manufacturers like Mostek, indicating a broader context of technology transfer and adaptation during the Cold War [10].
