 # Hign Endurance EEEPROM 
-In many situation we need to write the EEPROM memory frequently. Think about an Energy meter application. The energy parameter needs  to update frequently in EEPROM to persist the value for a long time. 
+## Problem Statement 
+In many situation we need to write the EEPROM memory frequently.For an energy meter application, The energy parameter needs  to update frequently in EEPROM to persist the value for a long time. 
 Let's Think about a situation. 
 I need to write energy value in eeprom after 10s interval.
 - total number of writes for one day would be 8640.

 For solving the eeprom wear out problem, I have developed an Arduino library  [RingEEPROM]().
 
-The idea is simple. As I cannot write/erase each cell more than 100k times, I will store my value in different cells in each write cycle. So let's consider our buffer size i 8. I am planning to write a byte in EEPROM. As I am using 8 cells for a single byte. Now I get 8*100k = 800k write cycles. That's huge. The bigger buffer size is, the more I get write cycles.  
+## Solution
+The idea is simple. I cannot write/erase safely each cell more than 100k times. Suppose I want to store a variable in EEPROM. What I will is, at First I will write the variable in first location, second time I will write the variable in the second location.Third time I will write the variable in the third location, Fourth time I will write the variable in the first location. I am repeating the pattern after 3 locatons. Thus I am getting 3 times endurance for a single variable.

+In this library, I will not store a single variable, I have developed the library such a way so that I can handle any size of buffer. 
 
+So for saving value in eeprom, we need two types of buffer 
+ 1. Parameter Buffer : This is the intended value we want to store in EEPROM
+ 2. Status Buffer: This buffer keeps track of my current location in buffer.
