PROJECT TITLE :

10T SRAM Using Half-VDD Precharge and Row-Wise Dynamically Powered Read Port for Low Switching Power and Ultralow RBL Leakage - 2017

ABSTRACT:

We have a tendency to gift, during this paper, a replacement 10T static random access memory cell having single ended decoupled scan-bitline (RBL) with a 4T scan port for low power operation and leakage reduction. The RBL is precharged at half the cell's supply voltage, and is allowed to charge and discharge in keeping with the stored information bit. An inverter, driven by the complementary knowledge node (QB), connects the RBL to the virtual power rails through a transmission gate throughout the browse operation. RBL increases toward the V DD level for a scan-one, and discharges toward the bottom level for a browse-0. Virtual power rails have the same price of the RBL precharging level throughout the write and the hold mode, and are connected to true offer levels solely throughout the scan operation. Dynamic management of virtual rails substantially reduces the RBL leakage. The proposed 10T cell in an exceedingly business sixty five nm technology is 2.forty seven× the size of 6T with ß = two, provides 2.three× read static noise margin, and reduces the scan power dissipation by fiftypercent than that of 6T. The value of RBL leakage is reduced by a lot of than three orders of magnitude and (I ON/ I OFF) is greatly improved compared with the 6T BL leakage. The leakage characteristics of 6T and 10T are similar, and competitive performance is achieved.
