It stores the program and system data — think of it as the removable program carrier for the controller. At 12 Mbyte of Flash-EPROM, it holds a fair-sized project with room for firmware updates or recipe variants. Rated for 500 000 write/delete cycles minimum, and data retention of 10 years after the final programming action (derated to 1 year if you're past 450 000 cycles). That endurance matters if you're regularly swapping programs on a multi-product line — you won't wear it out in a normal production lifespan.","metaTitle":"Siemens 6ES7954-8LE03-0AA0 SIMATIC S7 Memory Card, 12 Mbyte","metaDescription":"Siemens 6ES7954-8LE03-0AA0 SIMATIC S7 memory card for S7-1X00 CPU/SINAMICS. 12 Mbyte Flash-EPROM, 3.3 V, 500k write cycles, 10 yr retention.
