Hello,

Can this memory be ordered as lot sorted for the standby current?  Can you provide the manufacturing distribution for the standby current?

Hi Team,

I am working on CY62157EV30LL 45ZXi SRAM chip on imx53 processor connected through EIM interface.
1.When I write data , it hsows as written proper data but when reading it shows same 2 byte data reading for other 2 bytes also.
Example, 0x12345678 is written , when read backs it shows as 0x12341234

2. When I read for next address and so on , it shows the previously read value only like 0x12341234 as shown below
debian@arm:~$ sudo ./devmem2 0xf0000000 w 0x12345678
/dev/mem opened.
Memory mapped at address 0xb6fed000.
Value at address 0xF0000000 (0xb6fed000): 0xABCDABCD
Written 0x12345678; readback 0x12341234
debian@arm:~$ 
debian@arm:~$ 
debian@arm:~$ 
debian@arm:~$ sudo ./devmem2 0xf0000000
/dev/mem opened.
Memory mapped at address 0xb6ff0000.
Value at address 0xF0000000 (0xb6ff0000): 0x12341234

debian@arm:~$ sudo ./devmem2 0xf0000004
/dev/mem opened.
Memory mapped at address 0xb6fde000.
Value at address 0xF0000004 (0xb6fde004): 0x12341234
debian@arm:~$ sudo ./devmem2 0xf0000008
/dev/mem opened.
Memory mapped at address 0xb6fbe000.
Value at address 0xF0000008 (0xb6fbe008): 0x12341234

3.Can anyine tell me what are the working timing parameters to be configured on imx side for cy6215 sram chip.

4.How to change the EIM frequency

Please help to check the chip, may i know the whether the chip construction is correct

Low consumption SRAM "CY62187G30-55BAXI
About
A problem has occurred that causes a mismatch in CRC values.
When we check the waveform, the address setting for readout is correct,
However, the 0's and 1's are changing in a part of the readout data.
Two consecutive readouts are successful.
CY62187G30-55BAXI is equipped with ECC,
Is this a negative effect of having ECC installed?
Please give us information on how ECC works (what kind of processing it does).

The model number is: CY6218G30-55BAXI.
Please let us know the following.
(1) Is it possible to disable the power-saving mode?
(2) How long does it take for the power saving mode to become effective?
(3) How long does it take (typ, max) to recover (disable) from the power saving mode?
