Your requirement is 524288 bits i.e. 512kbits

It looks like in your case each block supports only 8k either as 512x16 or 256x32 rather than 10k.

Thus at 16 or 32 bits your requirement translates to 512k/8k = 64 blocks.

So if your write is 16 bits and read is 32 bits I don't expect doubling of blocks.

But look in the corners of data sheet regarding any hidden exceptions. It could be what you read is for write only read only ports and that your configuration is mixed on one port.
