Intel's 90nm MLC NOR flash memory can reach 1Gb storage density
Editor's recommendation: Intel's fifth-generation StrataFlash multi-level cell (MLC) flash memory product M18 is the first 1.8V, 90nm NOR device to achieve mass production. M18 is mainly aimed at the handheld device market, providing 256Mbit and 512Mbit single-chip capacity, and can be used in Intel's chip-scale packaging (CSP) to become a 1Gb chip. Its pins support PSRAM and SDRAM under shared and split bus architectures, with a read speed of up to 133MHz and a write speed of 0.5MB/s. At the same time, the product also supports 3MP cameras and MPEG4 videos.
Reader Comments:
1. The read speed is good, but the write speed is too slow. It is difficult to estimate its usability without knowing the price information.
2. Very good.
3. It's hard to get excited if you hear tomorrow that another flash memory is better. But this flash memory still sounds good.

SST's disk controller supports NAND flash memory for mass storage systems
Editor's Choice: Silicon Storage Technology's (SST) SST55LC100 CompactFlash NAND flash controller enables designers to build large-capacity storage systems based on standard NAND flash memory. The controller embeds SuperFlash technology and can change its firmware to support the latest NAND flash memory components by programming the embedded flash memory, while traditional mask ROM-based controllers require changing the mask program to integrate new NAND devices.
Reader Comments:
1. If too many storage units are used, the architecture supporting the image may have bottlenecks. How can memory management achieve data organization to improve throughput? How to solve this problem by using multiple units?
2. Worth paying attention to.
3. This product is of great significance to our signal processing needs.

Keil releases new 8051 MCU tools
Editor's Choice: The uVision3 integrated development environment (IDE) from Keil Software provides an important component in its PK51 and other development kits, covering all products of 8051 MCU. In addition to adding source code description, function wizard, template editing and search functions, the IDE also integrates Keil's C51 Version 8 compiler. In addition, uVision3 also provides a configuration wizard to shorten the time of generating startup code and configuration files, while its built-in simulator can simulate the target MCU, including instruction sets, on-chip peripheral interfaces, and peripheral signals. uVision3 provides a logic analyzer to synchronously display program variables as I/O pins and peripheral interfaces change.
The stereo headphone amplifier is also powered by a 3.3V power supply and can continuously provide an average of 25mW of power for each channel to drive a stereo 32Ω load with only 1% total harmonic distortion and noise.
Reader Comments:
1. It’s great to see support for mature products.
2. It is competitive in the market, but costs need to be further reduced.
3. We also plan to use the previous 8051 MCU code, which may be worth a look.
4. IDEs are mostly overhyped for dev... conventional implementations are even more questionable and require a lot of learning.

Samsung launches 256Mb GDDR4 device
Editor's Choice: Samsung Electronics has officially launched a graphics double data rate fourth generation (GDDR4) 256Mb video memory device for graphics card manufacturers for testing. GDDR4 memory devices can process game and video images at a speed of 2.5Gbps or 10GBps, which is equivalent to transferring 10 hours of DVD-quality video. The fastest video memory speed is currently limited to 1.6Gbps. As the resolution and content of games and videos increase, the image DRAM data processing performance needs to be further improved. However, when data is transmitted between the graphics chip and the local system, its inherent transmission delay limits the transmission rate. In order to achieve a 2.5Gbps transmission rate and reduce transmission delay, GDDR4 devices use data bus inversion (DBI) and Multi-Preamble technology, which increases the transmission speed by 56% compared to traditional graphics products.

Inphi launches FB-DIMM with small package, low latency and low power consumption
Editor's recommendation: Inphi's IN581AMB is the industry's first fully buffered DIMM (FB-DIMM) device with high-speed serial ports and DDR2 SDRAM interfaces, fully compatible with the JEDEC AMB specification. The IN581AMB can be used to improve the high-speed, serial, point-to-point connection performance between memory controllers and channel modules of next-generation servers and communication equipment. AMB technology is an innovative technology for memory products. It can achieve the transition from parallel bus to serial bus to memory-to-processor architecture, allowing it to be used like I/O in other communication systems.
Reader Comments:
1. As a user rather than a designer, this technology is transparent to me. However, people always hope that these advances can be put into practice as soon as possible. Large amounts of data files, CAD files, etc. need to be exchanged with increased transmission rates, and this type of technology will be welcomed.
