SRAM is much more expensive than DRAM, so it is mainly used as thecache memory insidethe integrated circuit that is a computer's CPU. DRAM is mainly used as the primary operational memory, running the OS and ap
Memory cards.Memory cards come in many formats -- secure digital card (SD) cards, microSD cards, memory sticks,CompactFlashcards -- and use flash memory for storage. Memory cards are commonly used to extend storage capacity in digital cameras, tablets and devices such as portable game consoles...
相比于直接将NAND Flash接入到Host 端,EMMC屏蔽了NAND Flash的物理特性,可以减少Host端软件的复杂度,让Host 端专注于上层业务,省去对NAND Flash进行特殊的处理。同时,EMMC通过使用Cache、Memory Array等技术,在读写性能上也比NAND Flash要好很多。而NAND Flash是直接接入Hos 端的,Host端通常需要有 NAND Flash Transl...
Flash attention中SRAM指的就是L1 cache/shared memory。 L2缓存:所有SM共享L2缓存。L2缓存不直接由用户代码控制。L1/L2缓存的带宽都要比显存的带宽要大,也就是读写速度更快,但是它们的存储量更小。 现在我们再理一遍GPU的计算流程:将数据从显存(HBM)加载至on-chip的SRAM中,然后由SM读取并进行计算。计算结果再...
FLASH是一种存储芯片,全名叫Flash EEPROM Memory,通过程序可以修改数据,即平时所说的“闪存”。 闪存可以在软件的控制下写入和擦写数据。其存储空间被分割成相对较大的可擦除单元,成为擦除块(erase block)。…

经过多年发展,Cache Read/Program及多路并发技术已发展得较为成熟,近年来的变化相对较小,但NAND Flash总线频率提升技术一直在蓬勃发展,并且近年来有加速演进的趋势,下面我们将结合ONFI协议演进来感受一下NAND Flash接口速率的演进。 2.ONFI接口演进历史 ONFI (Open NAND Flash Interface)组织成立于2006年5月,致力于...
外置FLASH读写实验 Flash,全名叫做Flash EEPROM Memory,即平时所说的“闪存”,它结合了ROM和RAM的长处,不仅可以反复擦除,还可以快速读取数据,STM32运行的程序其实就是存放在Flash当中 2023-03-01 14:56:52 STM32H7代码运行在外置flash的部分相关资料分享 场景项目中需要用到STM32H750这款ARM cortex-M7内核的...
First, FlashStore introduces flash as a cache in the memory hierarchy between RAM and hard disk so that the flash memory holds a “working set” of data—information a computer is most apt to need. FlashStore tracks data use so that, as data becomes less frequently accessed, it eventually...
it fits under the LinuxVirtual File Systembut does not use the file system’s buffer cache. It is designed to minimize the number of times that the flash memory must be erased. The flash memory is organized as a queue; new data is written at the tail of the flash queue and old data...
