Although in NAND gate pmos are in parallel and in NOR they are in series, so NAND gate is faster than NOR.
The NAND gate is a gate that produces a logic 1 output only when all of its inputs are logic 0. The NOR gate is a gate that produces a logic 1 output only when one or more of its inputs are logic 0.
Most motherboards that do not have an ECC function within the BIOS are still able to use a module with ECC, but the ECC functionality will not work. Keep in mind, there are some cases where the motherboard will not accept an ECC module, depending on the BIOS version.
NOR Flash memories range in density from 64Mb to 2Gb. Because of its higher density, NAND Flash is used mainly for data storage applications.
EEPROMs allow individual bytes to be erased and reprogrammed, unlike EPROMs. They can maintain its state through power cycles (on/off), like a PROM or EPROM. The capacity of EEPROMs is determined by the number of transistors on the silicon die.
Flash memory is different from RAM because RAM is volatile (not permanent). When power is turned off, RAM loses all its data. Flash can keep its data intact with no power at all. A hard drive is also permanent (non-volatile) storage, but it is bulky and fragile.
NOR Flash Memory A type of flash memory where cells are arranged horizontally in a semiconductor. Flash memory can be classified based on the electrical circuit alignment within the semiconductor chip.eMMC
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed.
At the cost of a little money and performance, ECC RAM is many times more reliable than non-ECC RAM. And when high-value data is involved, that increase in reliability is almost always going to be worth the small monetary and performance costs. In fact, anytime it is possible to do so, we would recommend using ECC RAM.Industrial SD
Flash storage is technically faster and newer than SSD storage; it just wouldn't be nearly as cost-effective to run on flash memory alone.
