TME: popular FLASH memories from GigaDevice

FLASH memories are used in most devices containing a microcontroller or a microprocessor. Currently, they are a must due to the increasing level of complexity of modern applications. FLASH memories, available in two versions, are used in substantially different applications. Taking into account the ratio of price to capacity, in mass memories intended for storing e.g. multimedia files (such as graphic or audio files) NAND memories are mostly used. 

NOR memories proved to be a better solution for microcontrollers without program memory. They are equipped with error correction function which cannot be implemented in NAND FLASH memories. Error correction function stores microcontroller or microprocessor instructions, for which error-free data transmission is an absolute priority. Providing small amount of data in the fastest possible time is a requirement but at the same time large memory capacity is not necessary.

High read speed of larger data chunks is without any doubt a big advantage of NAND FLASH memories.  NAND FLASH memories use parallel and serial interfaces – it allows for saving resources. Even serial interfaces make it possible to achieve high data transmission speed. For this purpose, SPI interface capable of working in Dual-SPI and QSPI modes is applied. It is possible to increase bus bandwidth four times at the same frequency of operation. It means that with QSPI interface, data transmission speed will amount to even 480Mbit/s at bus operating frequency of 120MHz.

GigaDevice provides state-of-the-art technological solutions in the area of non-volatile memories and microcontrollers with ARM core.  All memories offered by GigaDevice use SPI interface for the purpose of communication. Thanks to this fact, it is possible to achieve high frequencies of operation, i.e. 80MHz, 104MHz, and 120MHz, what in case of SPI interface corresponds to 80, 104, and 120Mb/s. Memories form GD25LQ series can operate with frequency of 133MHz.

For more demanding applications, memories are equipped with dual-SPI and quad-SPI (QSPI) interfaces. Thanks to the use of 2 (for Dual-SPI) or 4 GPIO lines (for QSPI) instead of one-way input and output lines (MOSI and MISO), the basic bandwidth was increased two and four times, respectively.

NOR FLASH memories are the most important product group manufactured by GigaDevice. All memories are characterised by industrial operating temperature range from -40 to 85°C, what significantly increases the range of potential uses. They are available in several different packages, beginning from the most widely used SOP8 and TSSOP8 packages, and ending with the smallest USON8 package.

It is worth to be mentioned that as one of the few companies in the market, GigaDevice offers and develops NOR FLASH memories.
