Nowadays data storage is gaining more importance in human life. All electronic and digital devices need memory for reducing the power consumption. The concept of “more data in less space” is useful for increasing the system performance and overall system efficiency. Generally we used semiconductor memory as “SRAM”. SRAM can be abbreviated “Static Random Access Memory”. Many VLSI chip can have SRAM memory because of their large storage capacity and fast accessing time, where the word static indicates that it does not need to be habitually refreshed but the DRAM need habitually refreshed. DRAM can be abbreviated as “Dynamic Random Access Memory” which is another type of memory. Both the memories can be classified from “Random Access Memory: (RAM).

In this paper the power analysis of 6 transistor SRAM is compared with 7 transistor SRAM. As a result the power dissipation of 7 transistors is high when compared with 6 transistors. The power dissipation of 6T SRAM is about 2.991mW and the power dissipation of 7T SRAM is about 3.183Mw. SRAM are mostly used for mobile applications, because of their ease of use and low leakage of power. In this paper the schematic of 6T SRAM and 7T SRAM are drawn using DSCH software and the layouts are drawn using MICROWIND software.

In recent days, Static Random Access Memory has become the major part in digital world. Because which occupies the largest portion of SOC (system-on-chip). The device need SRAM memory mainly for device dissipate small amount of power. But the dynamic power dissipation causes problems in digital circuits because the dynamic power depends on supply voltage, switching frequency and output voltage swing. Dynamic power dissipation can be minimized by reducing the supply voltage. At the same time low supply voltage leads to performance degradation and also decreases the threshold voltage which in turn increases the sub threshold current hence the static power dissipation increases. This paper discuss about the power dissipation of 6 transistors and 7 transistors SRAM. It also includes the functional view of 6T and 7T SRAM cells.

A conventional 6T SRAM consists 6 transistors which form two cross coupled inverters. This bit cell can be read and write single bit data. When a bit is stored in memory the 6T SRAM behave like a latch. The cross coupled inverter pattern which causes large area consumption which is a drawback of 6T SRAM when compared to resistive load. Conventional SRAM with 6 transistors is shown in figure 1 and 6T SRAM have three states they are read, write and hold states.
