Home › Product CenterFlashSPI Nor FlashISSI
    In NOR flash, each cell has one end connected directly to ground, and the other end connected directly to a bit line. This arrangement is called "NOR flash" because it acts like a NOR gate: when one of the word lines (connected to the cell's CG) is brought high, the corresponding storage transistor acts to pull the output bit line low. NOR flash continues to be the technology of choice for embedded applications requiring a discrete non-volatile memory device. The low read latencies characteristic of NOR devices allow for both direct code execution and data storage in a single memory product.    
ISSIISSI is a technology leader that designs, develops, and markets high performance integrated circuits for the following key markets: (i) automotive, (ii) communications, (iii) digital consumer, and (iv) industrial and medical. Our primary products are high speed and low power SRAM and low and medium density DRAM. The Company also designs and markets NOR flash products and high performance analog and mixed signal integrated circuits. We target high-growth markets with our cost-effective, high-quality semiconductor products and seek to build long-term relationships with our customers. We have been a committed long-term supplier of memory products, including lower density and smaller volume products, even through periods of tight manufacturing capacity.
