1965
- The use of semiconductor RAM dates back to 1965 when IBM introduced the monolithic (single-chip) 16-bit SP95 SRAM chip for their System/360 Model 95 computer, and Toshiba used bipolar DRAM memory cells for its 180-bit Toscal BC-1411 electronic calculator, both based on bipolar transistors.

The earliest semiconductor memory dates back to the early 1960s, with bipolar memory, which used bipolar transistors. [9] Bipolar semiconductor memory made from discrete devices was first shipped by Texas Instruments to the United States Air Force in 1961.
Jan 1, 2022 · In 1970, the newly formed Intel company publicly released the 1103, the first DRAM chip (1 kbit PMOS dynamic RAM ICs), and by 1972 it was the best-selling semiconductor memory chip in the world, defeating magnetic core type memory.
Jun 20, 2016 · Often taken for granted, solid-state semiconductor memory is the enabler of the contemporary digital world. Today's memory chips pack billions of transistors onto single slivers of silicon and push the boundaries of both packaging and density.

Semiconductor memory made from discrete devices was first shipped by Texas Instruments to the United States Air Force in 1961. In the same year, the concept of solid-state memory on an integrated circuit (IC) chip was proposed by applications engineer Bob Norman at Fairchild Semiconductor. [10]
His brainstorm planted the seed for the invention of dynamic random-access memory, or DRAM, the semiconductor-based memory architecture used by the majority of today’s computers, servers and consumer electronics, including mobile phones, game consoles and digital cameras.
