ULTRARAM is a charge-based memory where the logic state is determined by the presence or absence of electrons in an FG (Front Gate). The FG is electrically isolated from the control gate (CG) by Al2O3 dielectric, and from the underlying channel by the InAs / AlSb TBRT heterostructure .
Virtex is the flagship family of FPGA products currently developed by AMD, originally Xilinx before being acquired by the former. [1] Other current product lines include Kintex (mid-range) and Artix (low-cost), each including configurations and models optimized for different applications. [2]
In the late 1980s IBM invented DDR SDRAM, they built a dual-edge clocking RAM and presented their results at the International Solid-State Circuits Convention in 1990. [ 6 ] [ 7 ] Samsung released the first commercial DDR SDRAM chip (64 Mbit ) in June 1998, [ 3 ] followed soon after by Hyundai Electronics (now SK Hynix ) the same year. [ 8 ]
Xilinx produced the first commercially viable field-programmable gate array in 1985 [3] – the XC2064. [5] The XC2064 had programmable gates and programmable interconnects between gates, the beginnings of a new technology and market. [6] The XC2064 had 64 configurable logic blocks (CLBs), with two three-input lookup tables (LUTs). [7]

Xilinx's Embedded Developer's Kit (EDK) supports the embedded PowerPC 405 and 440 cores (in Virtex-II Pro and some Virtex-4 and -5 chips) and the Microblaze core. Xilinx's System Generator for DSP implements DSP designs on Xilinx FPGAs. A freeware version of its EDA software called ISE WebPACK is used with some of its non-high-performance chips.
The DDR4 chips run at 1.2 V or less, [18] [19] compared to the 1.5 V of DDR3 chips, and have in excess of 2 billion data transfers per second. They were expected to be introduced at frequency rates of 2133 MHz, estimated to rise to a potential 4266 MHz [ 20 ] and lowered voltage of 1.05 V [ 21 ] by 2013.
A soft microprocessor (also called softcore microprocessor or a soft processor) is a microprocessor core that can be wholly implemented using logic synthesis.It can be implemented via different semiconductor devices containing programmable logic (e.g., FPGA, CPLD), including both high-end and commodity variations.
