static const 2D array gives Error L6220E

Hello, my application is utilizing almost all RAM.

Now i need to add a feature and for that i declare a 2D array:

static const char * states[][2] =
                                  {
                                     {"st10","st20"},
                                     {"st11","st21"},
                                     .
                                     .
                                     .
                                  }

I am using a chip with 32KB Ram. Without this new array memory consumption is as follows:

Program Size: Code=95100 RO-data=6428 RW-data=396 ZI-data=37728

once i add 17-th element in the array I get:

Error: L6220E: Execution region RW_IRAM1 size (32776 bytes) exceeds limit (32768 bytes)

Why do i get this error? Aren't static const arrays are stored only in flash memory?
