G00184   NMAH Catalog Number 1987.0487.042
TI number: G00184
Memory, dynamic random access - This device represents the first TI effort to make a large monolithic DRAM. The work was done in FEP 1 for the Equipment Group between October 8 and December 30, 1970.

Harvey Cragon of the Equipment Group was in charge of the project. The device used 32 TI standard 1K MOS DRAM'S patterned on a 2" slice. At that time, the 1K was the largest DRAM available. After probing, 17 good 1K's were wire bonded together and then to the external leads, resulting a 1K by 17 bits DRAM. Of the 170 slices processed on 1-1-1 material with fully corrected masks, 119 (70%) had 17 or more good 1K's at multi probe, and 46 (27%) were good at functional probe. Four of the packaged devices were assembled into 4K x 17 bits memory modules for demonstration purposes. Although no production resulted, the project was successful in demonstrating that TI had the design, mask making and front end and capability to produce complex memory products. It also provided guidance to the Equipment Group with regard to using MOS memories in ASC and other applications. Two historical memos are in the file.

TI number: Y00346
Memory, Dynamic Random Access - These devices are from early engineering experimental lots of the first 4 MBit DRAM which was announced by TI in October, 1985. See Y00345 for more detailed information.

These packages are not sealed; and the lids are attached with tape to permit viewing. Although these are standard packages, the may not be a type that will be used in production. Y00345 & 6 were submitted as "most significant" development of 1985.

TI number: G00330
Wafer, Memory - This slice is from an initial production lot of 64K DRAM's on 125 mm. slices processed in the TI Japan Miho MOS 1 Front End. Processing was completed for shipment on July 10, 1982.

July,1982, was the first month of shipment of 125mm. slices from Miho MOS 1, and the conversion was completed in November, 1982. The five special chips on the slice are test chips to be available for slice evaluation purposes. Placing such chips on slices has been standard TI procedure. For information on the introduction of the 64K DRAM, see G00116.

Memory Chip Display - Displayed in a Lucite desk paperweight is a chip of the first four million bit DRAM. It was announced by TI in October 1985, and classified as an experimental device. It was also the first truly three dimensional VLSI circuit.

The device contains 4,194,304 memory bits in a 1 cm. square chip, utilizing 8.4 million components. A major feature of the design is a three dimensional trench transistor cross point cell. The technology is a 1 micron double level metal CMOS. At the time of the initial documentation (3/5/86), a testing program was underway, and release for production had not been scheduled.

G00183   NMAH Catalog Number 1987.0487.276
TI number: G00183
Wafer - This slice is from the first TI effort to make a large monolithic DRAM. The work was done in FEP 1 for the Equipment Group between October 8 and December 30, 1970.

The device is a 1K x 17 bits MOS DRAM. The process consisted of putting 32 standard 1K DRAMS on a 2" slice. Slices were multi probed, and those with 17 or more good 1K chips were accepted for further processing. See G00184 and G00185 for additional information. FEP1 was the result of the first TI program to build a slice processing facility utilizing the maximum practical mechanical handling and computer control. The program was known as the Front End Project.
