        Cypress had the following issue with the CY7C131E/131AE/136E/136AE Dual Port Static RAM:Chip Enable pin (CE) does not tristate I/Os of the Dual Port RAM under certain input conditions. As per the errata, the issues were supposed to be fixed by April 2012. Have the issues been addressed?

        The earliest date code for the new fixed "E" version components is 1207. This corresponds to the marking on the device in the YYWW format (YY-Year, WW-Workweek) Any date code on or after 1207 indicates the new fixed ‘E’ version components. This means any device with a date code of 1207, 1208,...,1213 etc., are the new fixed ‘E’ version components which do not exhibit the “Chip Disable Issue”.
