On: HPE unveils The Machine, a single-memory computer with 160 terabytes of memory

You made a math error:

You can encode about 300 addresses, at 36+8 = 44 bits per item, not 45 addresses, at 36*8 = 288 bits per address.

The bits are additive, because we're storing an address and data, not a byte of data per bit of address.

thanks, corrected.
