Memory is used to store data in the different forms such as audio, video, text etc. for different purpose. EPROM, PROM and MASKED are read only type of memories. DRAM, SRAM and SDRAM are read write type of memories. NVRAM, FLASH and EEPROM are most widely used hybrid memories in the ...
System having memory devices operable in a common interface DRAM and SRAM devices have a NAND interface mode (pins whose address and data are identical to one another are commonly used), directly being coupled to buses (an address/data bus and a control bus) of a NAND-type flash memory dev...

NAND闪存 NAND闪存(NAND Flash Memory) 一种半导体单元串联排列的闪存。 由于NAND闪存是垂直排列单元(即存储单位)的结构,因此可以在狭小的面积上制作很多单元,从而实现大容量存储。根据半导体芯片内部电子电路的形态,闪存分为串联连接的NAND闪存和并联连接的NOR闪存。 NAND闪存易于增加容量,改写速度快,而NOR闪存读取速度快...
NOR Flash is widely used as a direct replacement for regular ROM memory, the NAND Flash on the other hand is not that popular, maybe due to the different access approach, different interface and specific operation requirements although they are excellent solution when big storage is required. The...

NAND flash memory is a type of non-volatile storage that is widely used in consumer electronics devices. It is found in gadgets such as digital cameras, smartphones, tablets and laptops. NAND flash memory offers fast read and write speeds, as well as high capacity storage. There are two t...
This paper presents fundamental information about NAND Flash memory used in Embedded Systems. It discusses various aspects of this storage media such as interface, architecture, error source and error correction as well as software required for building
1.为什么会出现坏块由于NAND Flash的工艺不能保证NAND的Memory Array在其生命周期中保持性能的可靠,因此,在NAND的生产中及使用过程中会产生坏块。坏块的特性是:当编程/擦除这个块时,会造成Page Program和Block Erase操作时的错误,相应地反映到Status Register的相应位。
