AMD Company already acquired the license for the use of Z -RAM technology ( second generation ) , but they still confused : what products will use such memory type ?. AMD declared, that Z -RAM technology will not be used in the production of 65 nm processors cache. IBM company decided to equip its 45 nm processors with eDRAM cache . It cannot be excluded that AMD can follow this example, after preserving license on Z -RAM for other purposes.
Hynix this entire year looks at Z -RAM , and manifests serious interest in this technology. Therefore, to 2010-2011 we can see the first products, created with the aid of Z technology .
In comparison with SRAM memory , the memory type Z -RAM possesses five times larger density. In comparison with DRAM this index in Z -RAM is twice higher. Z -RAM can consume the same quantity of electric power as DRAM, but in this case its faster and it is more compact . Now Z -RAM models can operate at 500 MHz frequency - this is not so much, but with equal area Z -RAM memory can have five times larger volume.
Z -RAM requires simpler equipment and simpler technological processes in comparison with DRAM. To produce Z -RAM is possible only with the use of SOI technology . It is assumed that Z -RAM memory will start from memory modules , processors and products with high integration degree .
