The NOR Flash Memory forum discusses critical safety features for automotive and industrial systems, and Semper NOR Flash Memory with ASIL-B compliant and ASIL-D-ready.
The HyperFlash NOR Flash memories Forum offers discussions on automotive advanced driver assistance systems (ADAS), automotive instrument cluster, automotive infotainment systems, and communication equipment.
HyperRAM™ memory Forum discusses self-refresh DRAM operating on the 12-pin HyperBus interface. With a read throughput up to 333 MB/s, the HyperRAM for SoCs with limited on-board RAM providing external scratch-pad memory for fast read and write operations.
Non-volatile RAM forum discusses Technology such as F-RAM and nvSRAM, which combine non-volatile data storage up to 16Mbit density with the high performance of RAM. These low-power memories offer high endurance, high data retention and instant non-volatility without external battery back-up, enabling system reliability and cost reduction.

I am looking at the 25 Series Nor Flash memories and was wondering whether a verilog/vhdl implementation of a memory controller which can connect to this device in QSPI mode exists.Show Less
We are using a Spansion FL064LIF01 flash chip and are having issues with the flash chip where the configuration registers 2 & 3 have the binary codes wiped all to 0. Any ideas on what can cause this? We found in the specifications that a non-stable power supply during the register writing can cause this but have yet to be able to replicate the issue by cycling power while writing to the registers.Show Less
I am trying to run simulation auto-discovery mode on s25fl512s.
Something weird in the s25fl512s.sv model in the SFDP signature, it looks like it is not aligned with s25fl512s SPEC.
For example, address 1120h in the SFDP in the SPEC should hold the value 50h:
while in the model verilog, it looks like there is a shift of 1 address, the value 50h is on address 1121h:
Is it a problem in the model?
We will use CY62137FV18 as 1-Mbit and need to know how A16 pin should handle.
Does A16 pin pin have pull-up or pull-down resister internally ?
Otherwise should external pull-up or pull-down resistors be provided for A16 pin ?
When using CY15B102Q-SXET originally produced by your company, we found that the side of the pin of CY15B102Q-SXET(SOIC-8 package) does not tin, so we need to increase the soldering iron temperature and welding time to repair the solder joint of the pin. But this method will cause hidden trouble to the quality of the chip.
Subsequently, our company transferred ten CY15B102Q-SXET from the warehouse. Before any treatment, all the chip pins showed a dull and dull state; After operation according to method 2003.1 weldability of "GJB548B-2005 Test Method for Microelectronic Devices", all chip pins show bright coating, continuous tin surface, full coating and good tin from the front view; When all the chips were raised to observe the side of the pins, it was found that there were pitting points, no wetting of the coating and discontinuous tinning on the side of the pins.
We believe that this situation is not the cause of preservation, but the quality of the device reference script. If it is a preservation problem, it should be that the entire pin is not oxidized on the tin; However, after the test, the pin face, the front heel, the back heel to follow the tin are particularly good, only the two sides of the pin on the tin effect is particularly poor.
Could you tell us how we should handle this situation? Looking forward to your reply very much.

I used chip erase and sector erase but write operation is not performing. I read the device ID but i cannot read what i am writing. I am getting "0xFFFF" when i perform read operation. Can i know any solution to solve the problem.Show Less
i am getting error in address.
it is not reading address in correct address format.
my base address is 60000000+555, but it reading as 0000554 and 0000556.Show Less
