nor flash 与 nand flash 的区别
Beside the different silicon cell design, the most important difference between NAND and NOR Flash is the bus interface. NOR Flash is connected to a address / data bus direct like other memory devices as SRAM etc. NAND Flash uses a multiplexed I/O Interface with some additional control pins. NAND flash is a sequential access device appropriate for mass storage applications, while NOR flash is a random access device appropriate for code storage application.NOR Flash can be used for code storage and code execution. Code stored on NAND Flash can't be executed frome there. It must be loaded into RAM memory and executed from there.

gebi1218 发表于 2010-5-25 22:32:00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，不能将某些位拉高，这会造成Page Program和Block Erase操作时的错误，相应地反映到Status Register的相应位。总体上，� ......
谈谈Flash MMORPG的地图技术
在开发基于网页的Flash MMORPG游戏时，地图技术往往是最先被提及的。玩家的大部分游戏时间都是在地图上度过的，如何实现美观高效的地图效果，是每个技术人员都头疼过的。对于现在的2D游戏来说，如今的CPU/显卡和内存已经足够强劲了，因此很少需 ......
