stm32内部有两种存储器一种是ram和一种FLASH闪存 。
（1）STM32F10xxx内置64K字节的静态SRAM。它可以以字节、半字(16位)或全字(32位)访问。SRAM的起始地址是0x2000 0000。
我们可以理解成内存 ram类型的存储器掉电和数据会丢失。即stm32f1xx的内存只有64k这么大。
（2）高性能的闪存模块有以下的主要特性：
● 高达512K字节闪存存储器结构：
闪存存储器有主存储块和信息块组成：
─ 主存储块容量：
小容量产品主存储块最大为4K×64位，每个存储块划分为32个1K字节的页(见表2)。
中容量产品主存储块最大为16K×64位，每个存储块划分为128个1K字节的页(见表3)。
大容量产品主存储块最大为64K×64位，每个存储块划分为256个2K字节的页(见表4)。
互联型产品主存储块最大为32K×64位，每个存储块划分为128个2K字节的页(见表5)。
─ 信息块容量： 互联型产品有2360×64位(见表5)。 其它产品有258×64位(见表230/754、表3表4)。
闪存存储器接口的特性为：
● 带预取缓冲器的读接口(每字为2×64位)
● 选择字节加载器
● 闪存编程/擦除操作
● 访问/写保护
我们可以理解flash就是norflash或者nandflash或者rom 掉电后数据仍然存在的
程序运行时在ram中运行 程序代码是和数据是放在flash中
而堆和粘是在内存ram中分配的。
下面为一个stm32的map文件 里面可以查看一下信息分配
