16 Mbit parallelle nvSRAM'er med unikke features
Cypress introducerer som de første nvSRAM'er, der understøtter ONFI og Toggle synkrone interfaces, hvilket gør det muligt at forbinde direkte til NAND buscontrollere.
Cypress Semiconductor has introducet a family of16-Mbit non-volatile static random access memories (nvSRAMs), including devices
with synchronous NAND flash memory interfaces. The family marks the industry’s
first non-volatile SRAM memory that can interface directly with Open NAND Flash
Interface (ONFI) and Toggle NAND bus controllers.
Cypress's nvSRAM portfolio to address Solid State Drives (SSD) for enterprise
systems, high-end Programmable Logic Controllers (PLC), high-speed data/error
loggers in storage, and networking equipment.
The 16-Mbit nvSRAMs offer
access times as low as 25 ns, making them the fastest asynchronous non-volatile
RAMs on the market. The new devices are offered with an optional integrated
Real-Time Clock (RTC) that is not available in competing solutions.
enables time-stamping of critical data to be logged. Cypress nvSRAMs feature
infinite read, write and recall cycles, with 20-year data retention, making them
the best solution for applications requiring continuous high-speed writing of
data and absolute non-volatile data security.
family pushes the envelope of speed, density, and performance while delivering
the same superior reliability that is the hallmark of our nvSRAM portfolio, says said Babak Taheri, Vice President of the Non-Volatile Products Business Unit at
Cypress. - - - The synchronous NAND interfaces open multiple new markets to Cypress
nvSRAMs and add to the breadth and flexibility of our overall non-volatile
offerings.
The ONFI NAND interface nvSRAM supports the ONFI 3.0 NV-DDR
interface (100MHz) and the ONFI 3.0 NV-DDR2 interface (200MHz). The Toggle NAND
interface nvSRAM is compatible with Toggle 2.0 NAND controllers for DDR
operation at 200MHz.
Both ONFI and Toggle versions support single-channel
operations in x8 and x16 data bus widths, and dual- and quad-channel operations
in x8 bit data bus width, which allows operations of up to 400 million
transactions per second.'
The
16-Mbit nvSRAM family is sampling today, with production expected in the first
quarter of 2013. The CY14V116Fx ONFI and Toggle NAND devices operate on a 3V
core, 1.8V IO supply, and they are each available in a 165-ball FBGA package.
Both the asynchronous devices with and without RTC are offered in data bus
widths of 8 bits, 16 bits and 32 bits, and at different power supply levels of
2.5V, 3V, and 5V. They are available in 44-pin TSOPII, 48-pin TSOPI and
165-ball FBGA packages.
nvSRAMs
instead of a battery, making the devices compatible with standard PCB assembly
processes. Cypress’s nvSRAMs are ROHS-compliant and directly replace SRAM,
battery-backed SRAM (BBSRAM) and EEPROM devices, offering fast non-volatile data
storage.
place automatically at power down. On power up, data is restored to the SRAM
from the non-volatile memory. In Metering, Industrial, Automotive and RAID
applications, nvSRAMs offer high-speed data transfer while ensuring data
integrity in case of power outages, without the need for a battery.
