An SRAM-programmable field-reconfigurable memory by Tony Kai-Kit Ngai Download PDF EPUB FB2
This paper describes the design and implementation of an SRAM-Programmable Field-Configurable Memory (FCM), which has the flexibility to form over two hundred different memory configurations, each with up to four individual memories. Since their introduction, SRAM-programmable FPGAs have become very popular.
Carter, Hsieh [, ], Kean, Furtek, Hastie, Kawana, Muroga, Ebeling, Chow, Hauck, Hill and Britton [Britton ] and Cliff have all proposed SRAM-programmable by: 1.
Field-Programmable Gate Arrays Most current FPGAs are SRAM An SRAM-programmable field-reconfigurable memory book (Figure 1 left). SRAM bits are connected to the configuration points in the FPGA, and programming the SRAM bits configures the FPGA.
Thus, these chips can be programmed and reprogrammed as easily as a standard static RAM. This paper describes the design and implementation of an SRAM-Programmable Field-Configurable Memory (FCM), which has the flexibility to form over two hundred different memory configurations.
In this book the SRAM is used as the reference device for the discussions describing the basic functional blocks of a memory device, the various faults related to that function, and various tests to detect each type of fault. Later in this book other memory device types are discussed by describing the differences between the SRAM and that device.

Our radiation-hardened memories provide aerospace and military systems highly reliable, solutions for intense radiation environments. Read more. SRAM is the most precious memory commodity on the Arduino. Although SRAM shortages are probably the most common memory problems on the Arduino.
They are also the hardest to diagnose. If your program is failing in an otherwise inexplicable fashion, the chances are good you have crashed the stack due to a SRAM shortage. * Detected by first initializing the entire memory to an expected value x or x’.
Any subsequent march element operation that reads the expected value x and ends by writing x’ detects fault C - Fault D: * The memory my return a random result.
The fault must be generated when A x is written, and detected when either A w and A v is read. Your browser does not support all of our website’s functionality. For an improved shopping experience, we recommend that you use the most recent versions of Google.

SRAM (static random access memory) memory, the main theme of this blog post, has to do with logic gate flip-flops or rather gated D latches. SRAM is usually the type of memory used for the CPU's L1, L2, and L3 cache memory, memory that is placed nearby so that the CPU has quick access to the memory while processing programming instructions.
Serial SRAM is a standalone volatile memory that offers designers an easy and inexpensive way to add more RAM to their application. These 8-pin low-power, high-performance SRAM devices have unlimited endurance and zero write times, making them ideal for applications involving continuous data transfer, buffering, data logging, audio, video.

SRAM (Static Random Access Memory) is available at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many Static Random Access Memory manufacturers including Alliance Memory, Cypress, GSI Technology, IDT, ISSI, Microchip, & many more.
Please view our large selection of Static RAM below. RAM stands for Random Access Memory. SRAM stands for Static Random Access Memory. RAM is a volatile type of memory which is the most basic form of memory used in computer systems.
SRAM is a type of RAM which holds its content until power is connected. SRAM is expensive than Dynamic Random Access Memory.
A RAM memory (R andom A ccess M emory) is a type of memory which has these two main characteristics: It loses its data when the power is turned off (it's volatile). Reading and writing operations are very quickly. It doesn't matter the physical location of data inside the memory, any piece of data can be returned in a constant time.
Short for static random access memory, SRAM is computer memory that requires a constant power flow to hold information. Power consumption varies widely based on how frequently the memory is accessed. Although quicker than DRAM, SRAM is more expensive and holds less data per unit ore, it is more commonly used in cache and video card memory only.
SRAM or Static Random Access Memory is a form of semiconductor memory widely used in electronics, microprocessor and general computing applications. This form of semiconductor memory gains its name from the fact that data is held in there in a static fashion, and does not need to be dynamically updated as in the case of DRAM memory.

The reduction in configuration memory bits will reduce not only the area of the FPGA architecture, but also the configuration time and the size of the external memory used to store the bitstream.
The CLB proposed in  allows sharing of memory vectors between 2 LUTs (as shown in Figure 1) on which NPN-equivalent functions are mapped.
An overcurrent protection circuit for input/Output (I/O) buffers for a Field Programmable Gate Array wherein short circuits can be detected and the output current limited so as to avoid damaging the device. I/O buffers having the overcurrent protection circuit can detect a contention between the buffers.
In order to eliminate the contention, certain I/O buffers will go into a noncontending state. Ngai, Kai-Kit Tony, “An SRAM-Programmable Field-Reconfigurable Memory,” Manuscript Thesis, The University of Toronto Library, Aug. 18,pp.
