Process for making and programming and operating a dual-bit multi-level ballistic MONOS memory

A fast low voltage ballistic program, ultra-short channel, ultra-high density, dual-bit multi-level flash memory is described with a two or three polysilicon split gate side wall process. The structure and operation of this invention is enabled by a twin MONOS cell structure having an ultra-short control gate channel of less than 40nm, with ballistic injection which provides high electron injection efficiency and very fast program at low program voltages of 3~5V. The cell structure is realized by (i) placing side wall control gates over a composite of Oxide-Nitride-Oxide (ONO) on both sides of the word gate, and (ii) forming the control gates and bit diffusion by self-alignment and sharing the control gates and bit diffusions between memory cells for high density. Key elements used in this process are: 1) Disposable side wall process to fabricate the ultra short channel and the side wall control gate with or without a step structure, and 2) Self-aligned definition of the control gate over the storage nitride and the bit line diffusion, which also runs in the same direction as the control gate. The features of fast program, low voltage, ultra-high density, dual-bit, multi-level MONOS NVRAM of the present invention include: 1) Electron memory storage in nitride regions within an ONO layer underlying the control gates, 2) high density dual-bit cell in which there are two nitride memory storage elements per cell, 3) high density dual-bit cell can store multi-levels in each of the nitride regions, 4) low current program controlled by the word gate and control gate, 5) fast, low voltage program by ballistic injection utilizing the controllable ultra-short channel MONOS, and 6) side wall control poly gates to program and read multi-levels while masking out memory storage state effects of the unselected adjacent nitride regions and memory cells. The ballistic MONOS memory cell is arranged in the following array: each memory cell contains two nitride regions for one word gate, and ½ a source diffusion and ½ a bit diffusion. Control gates can be defined separately or shared together over the same diffusion. Diffusions are shared between cells and run in parallel to the side wall control gates, and perpendicular to the word line.

Process for making and programming and operating a dual-bit multi-level ballistic flash memory

An fast program, ultra-high density, dual-bit, multi-level flash memory process, which can be applied to a ballistic step split gate side wall transistor, or to a ballistic planar split gate side wall transistor, which enables program operation by low voltage requirement on the floating gate during program is described. Two side wall floating gates are paired with a single word line select gate, and word lines are arranged to be perpendicular both the bit lines and control gate lines. Two adjacent memory cells on the same word line do not require an isolation region. Also, the isolation region between adjacent memory cells sharing the same bitline is defined by the minimum lithography feature, utilizing a self align fill technique. Adjacent memory cells on the same word line share bitline diffusion as well as a third poly control gate. Control gates allow program and read access to the individual floating gate. In addition to the dual-bit nature of the cell, density can be even further improved by multi-level storage. In one embodiment, the dual multi-level structure is applied to the ballistic step split gate side wall transistor. In a second embodiment, the dual multi-level structure is applied to the ballistic planar split gate side wall transistor. Both types of ballistic transistors provide fast, low voltage programming. The control gates are used to override or suppress the various threshold voltages on associated floating gates, in order to program to and read from individual floating gates. The targets for this non-volatile memory array are to provide the capabilities of high speed, low voltage programming (band width) and high density storage.

Packaging method for very high density converters

Meeting todays requirement in power supply technology demands significant technological advancement in optimizing circuit topology, components and materials, thermal and packaging designs. These requirements are being pushed mainly by continuously increasing power density and efficiency requirements. Ultimately, these trends will come to a point whereby limitations from the above mentioned technological advancements is dependent on one of the above, which is the packaging design. To realize this dependence, we need to look at the growing power systems for modern equipment out there. Let us enumerate some of the available AC adapters in terms of power densities of a 45 W adapter. Firstly, square type architecture introduced by Apple is about 7 W / in3, considering the packaging has a profile limitation whereby its AC plug is removable thus occupying relatively bigger chunk of the volume. The next one is by Asus of similar profile to Apple incorporating the AC Plug eliminating the socket assembly in the packaging; which packs about 9 W / in3. Lastly, the typical rectangular profile by Eos which is about 7 W / in3. As for this particular embodiment it is about 40% smaller in profile, in contrast to the 45 W Apple packaging, with increase power density of about 12 W / in3.
