Memory organization

The M93Cx6 memory is organized either as bytes (x8) or as words (x16). If Organization

Select (ORG) is left unconnected (or connected to VCC) the x16 organization is selected;

when Organization Select (ORG) is connected to Ground (VSS) the x8 organization is

selected. When the M93Cx6 is in Standby mode, Organization Select (ORG) should be set

either to VSS or VCC to reach the device minimum power consumption (as any voltage

between VSS and VCC applied to ORG input may increase the device Standby current).
