Lithographic Technology for 64 Mb DRAMs.

Intel ® Extended Memory 64 Technology ( Em 64 T )

Recent industry developments mark a milestone in the evolution of 64-bit computing. 64-bit computing has been around for a long time in mainframe, reduced instruction set computers (RISC), and, more recently, in Intel IA-64 Itanium® architectures. Now, 64-bit computing is being standardized and driven into volume markets by AMD and Intel in processors that are based on the mainstream x86 archit...

Design and Simulation of a 2GHz, 64×64 bit Arithmetic Logic Unit in 130nm CMOS Technology

The purpose of this paper is to design a 64×64 bit low power, low delay and high speed Arithmetic Logic Unit (ALU). Arithmetic Logic Unit performs arithmetic operation like addition, multiplication. Adders play important role in ALU. For designing adder, the combination of carry lookahead adder and carry select adder, also add-one circuit have been used to achieve high speed and low area. In mu...

Error Detecting Refreshment for Embedded DRAMs

This paper presents a new technique for on-line consistency checking of embedded DRAMs. The basic idea is to use the periodic refresh operation for concurrently computing a test characteristic of the memory contents and compare it to a precomputed reference characteristic. Experiments show that the proposed technique significantly reduces the time between the occurrence of an error and its dete...

Fully Programmable Memory BIST for Commodity DRAMs

3⁄4 In order to accomplish a high speed test on low speed Automatic Test Equipment (ATE), a new instruction based, fully programmable memory, Built-in Self-Test (BIST) is proposed. The proposed memory BIST generates a high speed internal clock signal by multiplying the external low speed clock signal from the ATE. For maximum programmability and small area overhead, the proposed BIST receives t...
