1. Introduction

It is a systematic collection of electronic health information about an individual patient. In developing and undeveloped countries, there are lots of systems for storing patient’s medical record. But these systems are not for Individual person. In most of developing countries, there is no any system for storing medical record. Here, I represent my example. I live at Shahdadpur in Sindh province, Pakistan. [1] Shahdadpur has population of about 2435800 but there is no any medical record saving system. In developing countries, many people live in rural areas and most of them are uneducated. They don’t have previous medical record because they don’t aware about benefits of keeping medical record. [2] In 1990, about 5 million people died worldwide as a result of injury 8.4 million people will die every year from injury, and injuries from road traffic accidents will be the third most common cause of disability worldwide and the second most common cause in the developing world. [3] Over the past decade, about 258 million people have been affected by natural disasters worldwide every year. Every year an average of 10,000 people die because of earthquakes. Floods account for about 46% of disaster-related deaths in the America. [4] The floods in Pakistan began in late July 2010 which affected the Indus River basin. Approximately one-fifth of Pakistan's total land area was underwater. According to Pakistani government data, the floods directly affected about 20 million people, mostly by destruction of property, livelihood and infrastructure, with a death toll of close to 2,000. It is estimated that by the year 2020. When a person gets injured in accident and become unconscious therefore doctor cannot get history. So, treatment is very difficult, in case of natural disaster, all the systems become partially or temporarily fail. People lose their medical record and doctors face difficulties in treatment due to lack of medical record. At that time, SMIC will be the best source for providing medical record and easy to utilize. Moreover, it will also provide medical test report who consume more time. We can save life of many people by using this SMIC because this card will provide history of injured persons without any delay. So, doctor will not need to ask with patient. It is efficient device for treatment. It is secure device by biometric system and also costs low price.

2.1. NAND Flash Memory

NAND Flash memory is Flash Memory. It is an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed. The NAND type is primarily used in main memory, memory cards, USB flash drives, solid-state drives, and similar products, for general storage and transfer of data. [5] Flash memories became very popular in electronic systems. They are used to store program and data information, they allow to update firmware in the field when product is already deployed. They allow storing an immense number of files in a small single chip. The NAND Flash cell is composed of a single FET transistor equipped with extra gate called floating gate which stores the extra charge with information. The set of transistors is connected in a row one by one drain to source building up an AND gate – to read information from the selected page bit line current flows through all transistors. The one from selected page defines actual bit value. At the beginning memory cell stored just single bit of information. However, the charge on the floating gate can be controlled with some level of precision, allowing to store more information than just 0 and 1.

Figure 3. Major Markets Driving NAND Flash

[6] On a NAND chip each bit (0 or 1, on or off) is stored physically by a specially designed transistor called a floating gate. The floating gate is electrically isolated from all other components by a layer of oxide. Electrically isolating the floating gate gives NAND flash the most important property that is data retention without power! (This is also known as non-volatile storage because voltage isn’t required for the memory to maintain its state).

The asynchronous interface is a simple interface composed of separate read and writes signals along with chip select command and address latch. The data bus can be 8 or 16-bit wide. Data transfers are executed using full size of the bus; however, commands and addresses are always transferred in 8-bit fashion. NAND flash memory reads and writes data in units called “pages.

Equation

The following equation (4) can be used to calculate the memory lifetime.

Without wear-leveling only 80 blocks are effectively used. Let’s calculate the lifetime for this case:

With wear-leveling, the whole memory is used, so 2048 blocks are reused - let’s calculate the lifetime of these 2048 blocks

2.2. Card Reader

A card reader is a data input device that reads data from a card-shaped storage medium. The first were punched card readers, which read the paper or cardboard punched cards that were used during the first several decades of the computer industry to store information and programs for computer systems. Modern card readers are electronic devices that can read plastic cards embedded with either a barcode, magnetic strip, computer chip or another storage medium. It is used to read, write and sharing the medical data.

2.3. Biometric System in Card

[7] Biometric technologies are defined as automated methods of identifying or verifying the identity of a living person based on unique biological (anatomical or physiological) or behavioral characteristics. Biometrics can provide very secure and convenient verification or identification of an individual since they cannot be stolen or forgotten and are very difficult to forge. [8] Fingerprint: Humans have used fingerprints for personal identification for many centuries and the matching accuracy using fingerprints has been shown to be very high [9]. A fingerprint is the pattern of ridges and valleys on the surface of a fingertip, the formation of which is determined during the first seven months of fetal development. [10] it stores the card holder's fingerprint inside the card and is only activated each time the card holder touches a sensor on the surface of the card.

3. Conclusions

The paper has described that the system and the research mechanism of SMIC which provides an immense help and support to individual person. Medical records help the doctor as well as patient. SMIC not only assists in treatment by providing patient’s history but also provides medical reports immediately in case of emergency because some reports consume more time. It also has some features like ease of data entry, easy to learn, reliability, ease of implementation in EMR, interactivity with other office systems, value for the money, physician satisfaction, staff satisfaction; and patient satisfaction. Allah says that if anyone saved a person, it would be as if he saved the whole humanity. No doubt, the best work is to help humanity.
