To find these memory mapped expansion ROMs during boot, PC BIOS implementations scan real memory from 0xC0000 to 0xF0000 on 2 kilobyte boundaries looking for a 0x55 0xaa signature, which is immediately followed by a byte indicating the number of 512 byte blocks the expansion ROM occupies in real memory.

为了在开机时找到这些记忆体映射的扩充唯读记忆体，PC BIOS 会扫描实体记忆体，从 0xC0000 到 0xF0000 的 2KB 边界中寻找 0x55 0xaa 记号，接在其后的是一个位元，表示有多少个扩充唯读记忆体的 512 位元区块占据真实记忆体空间。

As we know memory can be divided into the short-term memory and long-term memory.

如我们所知道的记忆可分为长期记忆和短期记忆。

Each SGI Origin 300 server has from 512 MB to 4 GB of local memory, which includes main memory and directory memory for cache coherence.

每个SGI的起源300服务器从512 MB到4本地内存，其中包括主存储器和高速缓存的一致性目录内存。

When FIFO is empty or partially empty, the LCDCDMA requests data fetching from the frame memory based on the burst memory transfer mode consecutive memory fetching of 4 words (16 bytes per one burst request without allowing the bus mastership to another bus master during the bus transfer.

当传送请求被位于内存控制器中的总线仲裁器接受时，将有连续的 4 个字的数据从系统内存送到外部的 FIFO。

The memory bus is coupled to a first plurality of memory modules corresponding to a first memory bank.

存储器总线连接到与第一存储体相对应的第一个多个存储器模块。

The memory bus is also coupled to a second plurality of memory modules corresponding to a second memory bank.

存储器总线也连接到与第二存储体相对应的第二个多个存储器模块。

When loading the memory, the tap cells must be viewed as 6 memory banks with 108 24-bit memory locations in each bank.

当加载的内存，水龙头细胞必须被看作是银行与108 6内存24位在各银行的内存位置。

This happens because if free memory falls below a minimum value, the host operating system continually frees up memory by swapping to disk to maintain that amount of free memory.

这种情况是因为空余的内存降低到了一个最小的数值，这时主机要不断地使用磁盘交换数据来释放内存。

Protected mode allows for 16M of memory but is also capable of protecting the operating system and programs from accident and deliberate destruction by users, a feature that is absent in the single-user 8088/8086 Virtual memory is a way of fooling the microprocessor into thinking that it has access to an almost unlimited amount of memory by swapping data between disk storage and RAM.

在保护模式下系统可用16M的内存寻址并且可防止操作系统或程序被用户不经意或故意破坏。这个特征是单用户8088/8086所不具备的。所谓虚拟内存就是通过在磁盘存储器与RAM中交换数据将微处理器骗过，使之认为它有无限大的内存寻址空间。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
