I'm trying to use the bram coregen from ISE. My part is the Spartan 3E 500K
gates with 20 of 18Kbit bram blocks for a total of 368640 bits (according t=
o
the datasheet).

However, the coregen isn't allowing me to fully use all available bits. By
trying different values, it shows me that (for example), an 8 * 2048 (=3D
16384 bits) memory consumes one 18Kbit block, which doesn't make sense to
me. Going over just by one causes it to consume 2 blocks. What's going on
here?

It won't let me do an 8 * 46080 (=3D 368640) bits memory. It tells me that
it's more than what's available on my device.
