AN12437 SDRAM Read performance

Hi.

According to AN12437 SDRAM read performance is three times lower then write performance, 111 vs 323 MB/s. Is there any good explanation why read performance is worse then write?

Hi @energycsdx,

I believe the following post will be very helpful in answering why RAM read is generally worse performing than RAM write: Solved: Re: iMXRT1176: poor OCRAM read performance - NXP Community.
