Description: 电可擦除可编程只读存储器EEPROM可分为并行和串行两大类。并行EEPROM在读写数据是通过8位数据总线传输，而串行EEPROM的数据是一位一位的传输。虽然与并行EEPROM相比，串行传输数据较慢，但它体积小、专用I/O口少、低廉、电路简单等优点，因此广泛用于智能仪器、仪表设备中。-Electrically erasable programmable read-only memory EEPROM can be divided into two major categories of parallel and serial. EEPROM read and write data in parallel through the 8-bit data bus transmission, while the serial EEPROM data transmission is a one. Although compared with the parallel EEPROM, serial transmission of data slower, but it is small, dedicated I/O port less cheap, simple circuit, it is widely used in intelligent instruments, instrumentation equipment.

Description: This module implements a Linux character-mode device-driver
for the processor s installed physical memory. It utilizes
the kernel s kmap() function, as a uniform way to provide
access to all the memory-zones (including the "high memory"
on systems with more than 896MB of installed physical ram).
The access here is read-only because we deem it too risky
to the stable functioning of our system to allow every user
the unrestricted ability to arbitrarily modify memory-areas
which might contain some "critical" kernel data-structures.
We implement an llseek() method so that users can readily
find out how much physical processor-memory is installed.
