CAMAS, WASH. Sharp Microelectronics of the Americas has begun offering stacked chip-scale memory devices with 32 Mbits of flash memory and 4 Mbits of SRAM. Sharp said the 16-bit LRS1337 and 8-bit LRS1333 are among the smallest mass-produced multichip memory devices for that capacity.
Both devices have an operating voltage range of 2.7 V to 3.6 V. Access times are 90 ns for flash and 85 ns for SRAM. They are available in a 72-pin package that measures 8 x 11 mm and is 1.4-mm high. Both are priced at $45 in 100-unit quantities.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
