4x4 Compact Array with One Transistor One Memristor Memory Element
Shalini Singh, Shyam Akashe

Abstract
Customary memories are facing acute design problems due to gradual scaling of CMOS technology. There is a great need of superseding the conventional memories by a device that could fulfil the emerging need of high density device and low power consuming memory designs (array) that are capable of delivering the prerequisite of any memory design to store data and instructions. Memristor is a device that can supersede the conventional CMOS based cell. It is a two terminal non-volatile multi-purpose device. Memristor can store input/output value, perform logic operations, can act as a switch, latch or flip flop. This paper concentrates on the working of Memristor and designing 4x4 Memristor based array (1T1M) and thus highlights the advantages of using Memristor and 1T1M(one transistor one memristor) array. Memristor used in this paper has been implemented with Verilog–A model in cadence virtuoso tool at 45nm technology. The average transient power was found to be 8.148 nW at 0.3V which shows that by employing Memristors, minimum voltage at which array is capable of retaining data is 0.3V.

Does Price to Book Value Predict Stock Price? Evidence from Nigerian Firms
Isah Shittu, Ayoib Che Ahmad and Zuaini Ishak

Abstract
The value a company is usually ascertained based on the markets values of its equity in the markets. Share prices of a company inform the public on the prospect of such stock hence, decisions on purchase or sales is determined. Price to book value multiple is one of the valuation multiples used to predict stock price of companies. However, arguments exist on whether the P/B multiple can be used to predict stock price of Nigerian firms. This study achieve this objective by examining effect of P/B multiple on stock price of 100 firms listed on the Nigerian Stock Exchange (NSE) covering 2009 to 2013 period data. Evidence from the ordinary least square (OLS) results reveals a significant positive relationship between price to book value and stock price of Nigerian listed firms. Therefore, we concludes that price-book value predict stock price of Nigerian listed firms. Hence, recommends the application of P/B value multiple in the prediction of future stock price.
